angeli buys a pair of jeans for $27. he pays $0.07 in sales tax for every dollar of the price. write an equation to show how to calculate the sales tax on the jeans.
Is there answer choices? It's simple but if you have something to chose from o can explain it to you better
so we'll say the total price is y and x is the number of dollars
y = x(0.7) + 27
in this caseĀ
y = 27(0.7) + 27
