Sales tax on a shirt is 0.07 times the cost of the shirt. The sales tax for a shirt is $1.26.

Question

Which equation could you use to find the cost, c, of the shirt before sales tax?

0.07 ÷ 1.26 = c
0.07 ÷ c = 1.26
0.07 • c = 1.26
0.07 • 1.26 = c

Answer 1

To find the cost \( c \) of the shirt before sales tax given that the sales tax is 0.07 times the cost of the shirt and the sales tax amount is $1.26, you can set up the equation based on the relationship between the sales tax and the cost:

\[ 0.07 \cdot c = 1.26 \]

So the correct equation to use is:

\[ 0.07 \cdot c = 1.26 \]

This matches the option:

0.07 • c = 1.26.
