Answer:
15 pencils
Step-by-step explanation:
5/2.5=x/7.5
cross product
2.5*x=5*7.5
2.5x=37.5
x=37.5/2.5
x=15
Answer:
To find out how many pencils you could buy for $7.50, you first need to see how much one pencil costs
The total of one pencil is 2.50/5
2.50/5= 0.50
Each pencil is a total of $0.50
Next you want to take 7.50/.50 to see how many pencils you could get
$7.50/$0.50= 15
You would be able to buy 15 pencils with $7.50
Hope this helps ;)
