Question

Veronica works at a music store last week she sold five more than three times the number of headphones that she sold this week. Veronica sold a total of 89 headphones over two weeks how many headphones did she sell this week?

Answer 1

Answer:

14 headphones

Step-by-step explanation:

Use algebraic manipulation. Let x be the number of headphones sold this week:

89 = x + (3x + 5)

Combine like terms:

89 = 4x + 5

Get the x's on one side:

84 = 6x

Divide:

14 = x

So, Veronica sold 14 headphones this week.
