Question

Adrian has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.

He buys a new bicycle for $322.09.
He buys 3 bicycle reflectors for $9.54 each and a pair of bike gloves for $22.01.
He plans to spend some or all of the money he has left to buy new biking outfits for $61.82 each.

Use the drop-down menu below to write an inequality representing oo, the number of outfits he can buy while staying within his budget.

Answer 1

4 outfits

Explanation:

So to find out how much he has left after all his purchases to buy new biking outfits we can add:

9.54 x 3 = 28.62

22.01 + 28.62 + 322.09 = 372.72

Now we subtract his budget by how much he has already spent:

620 - 372.72 = 247.28

He has $247.28 left for outfits so we can divide 247.28 by $61.82 (the amount per outfit) to find how many he can buy:

247.28 / 61.82 = 4

Adrian can buy 4 outfits.
