Question 15.
During September and October of 2008, the Grand Canyon National Park recorded a total of 792,426 visitors. If there were 359,396 visitors in October, how many people visited the park in September?

(C) 2,100
(D) 819

The number of crocodiles in west enclosure = 117

The number of crocodiles in east enclosure = 183

Also given, there are 7 times as many alligators as crocodiles.

Which means,

In west Enclosure In East Enclosure, Total number of alligators = 819+1281 Therefore, There are 2100 alligators.

Question 18.
Gardeners at The Seed Stop are planting vegetable seeds in trays. In each tray, there are 12 rows with 8 sections in each row. If they plant one seed in each section, how many plants will there be in 53 trays if all of the seeds germinate?

Question 26. Allison’s Bakery will donate$1,200 worth of baked goods to a school event. The school wants to order 12 loaves of holiday bread, 18 dozen biscuits, 12 dozen bagels, and 14 dozen multigrain rolls. Is the cost of the baked goods under the $1,200 donation limit? Explain how you found your answer. If yes, what could the school add to the order? If no, what could the school remove from the order? Answer: The total amount of the money =$1200

The cost of Holiday bread = $20 Number of holiday bread = 12 Now, The cost of Biscuits =$12

Number of biscuits = 18

Now, The cost of Bagles = $28 Number of bagles = 12 Now, The cost of multigrain rolls=$22

Number of multigrain rolls = 14 Now, The total of items =

240 + 216 + 336+308 = 1108

Which means, the school did not exceed the limit.
