Melanie has $660 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. She buys a new bicycle for $382.14. She buys 3 bicycle reflectors for $5.72 each and a pair of bike gloves for $27.55. She plans to spend some or all of the money she has left to buy new biking outfits for $46.63 each. Write an inequality representing, the number of outfits she can buy while staying within her budget.
x = amount of money left over
The amount of money left over equals the starting amount minus the expenses. x = 660  [382.14 + 3(5.72) + 27.55] {amount left over equals 660 minus the total expenses} x = 660  (382.14 + 17.16 + 27.55) {multiplied 3 by 5.72} x = 660  426.85 {added inside parentheses} x = 233.15 {subtracted} y = the number of outfits she can buy The price per outfit multiplied by the number of outfits, y, needs to be less than or equal to the amount left over, $233.15, to stay within her budget. 46.63y ≤ 233.15 {price per outfit multiplied by number of outfits is less than or equal to $233.15} Ask Algebra House
