(C) 3y+5
First you would distribute the 3 across the (y+4) to get 3y + 12, the you'd subtract 7 to get 3y+5
4x+y=3
-5x-8y=-6
C is the one that will help you solve it.

Answer: The girls collected 18 more aluminum cans than the boys.
Step-by-step explanation:
boys:
16 x 12 = 192
girls:
15 x 14 = 210
210 - 192 = 18
We want to perform a change of units from pound to ounces.
The equivalence is:
5.60 dollars/lb = 0.35 dollars/oz
We start knowing that the cost per pound is $5.60
We can write this cost as:
c = 5.60 dollars/lb
Now we need to use the relation:
<u>1 lb = 16 oz</u>
Then we can replace the "lb" in the denominator of c by 16 oz, we will get:
c = 5.60 dollars/lb = 5.60 dollars/(16 oz) = 0.35 dollars/oz
Then each ounce of strawberries costs $0.35
