Answer:
572.40
Step-by-step explanation:
First find the tax
540 * .06 = 32.4
Add this to the original cost
540+32.4 =572.40
$572.4 because 6% of the original cost, $540.00, is $32.4. So, after adding that to the original price you would get $572.4.
$68.97
The equation you have to use is I=p(1.45)
If you have a 45% increase to 100, the original price was $68.97.
1 square inch = 2.54^2 = 6.4516 square cms
So 5.60 in^2 = 6.60 * 6.4516 = 36.13cm^2 to nearest hundredth
