Unlock the Problem

A group of friends go to a local fair. Jayson spends S3.75.
Maya spends 3 times as much as Jayson. Tía spends $5.25 more than Maya. How much does Tia spend? Use the graphic organizer below to help you solve the problem. Read What do I need to find? I need to find ______Tia____ What information am I given? I need to use the amount spent by __Jayson_ to find the amount spent by and _Maya__ at the fair. plan What is my plan or strategy? I can draw a diagram to show ___Tia____ Solve The amount of money Maya and Tia spend depends on the amount Jayson spends. Draw a diagram to compare the amounts without calculating. Then, use the diagram to fìnd the amount each person spends. Jayson:$3.75
Maya: 3 × _$3.75__ = _$11.25__
Tia: _$11.25__ +$5.25 = __16.5__

So, Tia spent _$16.5_ at the fair. Try Another Problem Julie’s savings account has a balance of$57.85 in January.

Question 1.
Manuel collects $45.18 for a fundraiser. Gerome collects$18.07 more than Manuel.
Cindy collects 2 times as much as Gerome.
How much money does Cindy collect for the fundraiser?
First, draw a diagram to show the amount Manuel collects.
Then, draw a diagram to show the amount Gerome collects.
Next, draw a diagram to show the amount Cindy collects.
Finally, find the amount each person collects.
Cindy collects ___ for the fundraiser. Explanation:
Manuel collects $45.18 for a fundraiser. Gerome collects$18.07 more than Manuel,
So Gerome collects $18.07 +$45.18 = $63.25, Cindy collects 2 times as much as Gerome means 2 X$63.25 = $126.50, How much money does Cindy collect for the fundraiser? First, draw a diagram to show the amount Manuel collects. Then, draw a diagram to show the amount Gerome collects. Next, draw a diagram to show the amount Cindy collects. Finally, find the amount each person collects. Cindy collects$126.50 for the fundraiser.

Question 2.
What if Gerome collects $9.23 more than Manuel? If Cindy still collects 2 times as much as Gerome, how much money would Cindy collect? Answer: Cindy Collected$108.82,

Explanation:
Given Manuel collects $45.18 for a fundraiser, If Gerome collects$9.23 more than Manuel then
Gerome collected $45.18 +$9.23 = $54.41, Cindy collected 2 times as much as Gerome, So, 2 X$54.41 = $108.82, therefore money Cindy collected is$108.82.

Question 13.
Multi-Step At the farmer’s market, heirloom tomatoes cost $5.99 a pounds beefsteak tomatoes cost$3.19 a pound, and cherry tomatoes cost $2.99 a pound. Joe bought 2 pounds of each type of tomato. How much did he spend on tomatoes? (A)$21.35
(B) $12.17 (C)$24.34
(D) $18.16 Answer: (C)$24.34,

Explanation:
Given at the farmer’s market heirloom tomatoes cost $5.99 pounds, beefsteak tomatoes cost$3.19 a pound and cherry tomatoes cost $2.99 a pound. Joe bought 2 pounds of each type of tomato, heirloom tomatoes cost 2 X$5.99 pound = $11.98, heirloom tomatoes cost 2 X$5.99 pound = $6.38, cherry tomatoes cost 2 X$2.99 a pound = $5.98, Total tomatoes cost are$11.98 + $6.38 +$5.98 = $24.34. Question 14. Multi-Step Carnations cost$0.99 each, daisies cost $1.75 each, and lilies cost$2.26 each.
How much would an arrangement cost that is made with 3 carnations,
two more daisies than carnations, and twice as many lilies as daisies?
(A) $34.32 (B)$15.51
(C) $25.28 (D)$40.59
(D) $40.59, Explanation: Given Carnations cost$0.99 each, daisies cost $1.75 each and lilies cost$2.26 each.
The arrangement cost that is made with 3 carnations is 3 X ($0.99 +$1.75 + $2.26) = = 3 X$5.00 =  $15.00, Now two more daisies than carnations is (2 X$1.75) + $15.00 =$3.50 + $15.00 =$18.50 and
twice as many lilies as daisies is (2 X $2.26) +$1.75 = $4.52 +$1.75 = $6.27, therefore arrangement cost is$15.00 + $18.50 +$6.27 =\$40.59.
