Tracy wants to purchase custom-made bumper stickers to advertise her business. Two websites offer different deals:

Question

Website A: Pay a fee of $116.00, plus $0.50 per bumper sticker
or Website B: Pay a fee of $99.50, plus $0.65 per bumper sticker

At least how many bumper stickers must Tracy purchase in order for Website A to be the better choice? Note that “better” means cheaper! Show work.

Let x = number of bumper stickers. Write an appropriate inequality involving x and solve it algebraically. Write a sentence to carefully state the answer to the question. The sentence should have the form “Website A is the better choice if Tracy purchases at least ____ bumper stickers.”

Answer 1

Website A: Pay a fee of $116.00, plus $0.50 per bumper sticker
or Website B: Pay a fee of $99.50, plus $0.65 per bumper sticker
a: 116+.5x
b: 99.5+.65x
To find out how many bumper stickers you'd have to buy for the costs to be equal, set them equal to each other: 116+.5x=99.5+.65x. Then it would be one number off of that for the "better buy".
