Would it be division or multiplication
miv72 [106K]
In this situation, you would use division because when you divide the number of blankets by the number of boxes, you will get how many blankets were put into each kennel. And since there were 1,110 puppy blankets and 27 boxes, divide 1,110 by 27. This will get you the answer 41. This means that there are 41 puppy blankets in each box, and so the answer is D. 41.

A sum of money amounting to $4.15 consists of dimes and quarters. If there are 28
anastassius [24]

Answer:

there are 9 quarters and 19 dimes

Step-by-step explanation:

Let x be the number of dimes and y the number of quarters

-dimes: 0.1x

-quarters: 0.25y

-the total amount of coins : x + y = 28  

=> x = 28 - y

We have the equation:

0.25y + 0.1x = 4.15

0.25y + 0.1(28 - y) = 4.15

0.25y + 2.8 - 0.1y = 4.15

0.15y = 1.35

y = 9

x = 28 - y

  = 28 - 9

  = 19
