Nicole bought a meal in a town that has no sales tax. she tips 20%. select all meals nicole could buy for less that $15 total.

I'm missing some information... but I'll answer the question regardless

x=the cost of the meal

1.2x≤$15
divide both sides by 1.2
x≤$12.5

In short, this means that Nicole can buy anything that costs $12.50 or less.

The linear equation is: y=ax+b
