Answer 2

Part a) 1,275$
Part b) 125 apples

Explanation:

If 20 apples cost 300 dollars finding the cost of 85 apples should be quite simple. There are a few ways we can find the answer but the simplest way is by finding the cost per unit or how much each apple costs. Knowing the cost per unit we can easily multiply the cost by the number of units to find our answer.

Part a)
20 apples cost 300$

`(cost)/(unit) =cpu`

`300/20=15`

`cpu=15`

Now that we have the cost per unit, simply multiply the cost by the quantity:


`15*85=1275`

`=1275`

So the cost for 85 apples would be 1275$.

Part b)
20 apples = 300 dollars
1 apple = 15 dollars
85 apples = 1275 dollars

`15*125=1875`
125 apples = 1875 dollars.

1875 would get you 125 apples.

I hope this helps.
