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?

a. 0.75e = 3.50 – 0.50p
b. 0.50p + 0.75e = 3.50
c. 3e = 14 – 2p
d. 2p + 3e = 14

The answer is the option B

Step-by-step explanation:

Let

p------> the number of pencils

e------> the number of erasers

we know that

The total cost of pencils and erasers, is equal to the numbers of pencils multiplied by plus the number of erasers  multiplied by

so
