Translate Word Problems into Equations: Grade 7 Challenge

A store sells pencils for $0.50 each and erasers for $0.75 each. If you buy a total of 10 items and spend $6.00, create an equation to represent the number of pencils (p) and erasers (e).

• p + e = 8, 0.50p + 0.75e = 7.50

• p + e = 12, 0.50p + 0.75e = 5.00

• p + e = 10, 0.50p + 0.75e = 6.00

• p + e = 10, 0.50p + 0.75e = 5.50
