jeyben [28]

Answer:

She would pay $2.80 in sales tax.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Megan paid $2.52 in sales tax on an item that cost $36.00 before tax. How much in taxes for $40.00 before taxes?

$2.52 - $36.00

x - $40.00

Applying cross multiplication

$36x = 40*2.52$

$x = \frac{40*2.52}{36}$

$x = 2.8$

She would pay $2.80 in sales tax.
