Answer:
a. Equation: 0.8x+30 = 1.2x+14
b. Solution: 40 Stickers
Step-by-step explanation:
"per sticker" means there will be a variable which will be how many stickers he buys next to the price and the fee is the amount of money that will be added onto the fee price.
Company A equation: 0.8x+30
Company B equation: 1.2x+14
You will set these equal to each other to find the number of stickers which cost the same for both companies, then solve for x by doing inverse operations.
0.8x<u>+30</u> = 1.2x<u>+14</u> [subtract 14 from both sides]
<u>0.8x</u>+16 = <u>1.2x</u> [subtract 0.8x from both sides]
<u>16</u> = <u>0.4x</u> [divide 0.4 from both sides]
x = 40 [The solution is 40 stickers]
