Question

Alejandro bought $3.50 worth of pencils and erasers at the school store. Pencils cost $0.50 apiece, and erasers cost $0.75 apiece. Which equation written in standard form represents the number of pencils, p, and the number of erasers, e, that Alejandro bought?
0.75e = 3.50 – 0.50p
0.50p + 0.75e = 3.50
3e = 14 – 2p
2p + 3e = 14

Answer 1

Answer: $0.50p+0.75e=3.50$

Step-by-step explanation:

Given: The total price paid by Alejandro = $3.50

The cost of a pencil = $0.50

The cost of a eraser = $0.75

Let the number of pencils denoted by  'p' and the number of erasers denoted by 'e' that Alejandro bought.

Then according to the question, we have

The total cost of pencils and eraser bought by Alejandro =$0.50p+0.75e=3.50$

Therefore, the equation written in standard form represents the number of pencils, p, and the number of erasers, e, that Alejandro bought will be

$0.50p+0.75e=3.50$

Answer 2

I believe the answer is 0.50p + 0.75e= 3.50
