Patel bought a model rocket kit from a catalog. the price of the kit was 124.95. the state sales tax of 7% was added, and then a $10 charge for shipping was added after the sales tax. what was the total amount patel paid, including tax and shipping cost?

Firstly we need to find out how much is 7% from $124.95:

7% * 124.95 =
= 7/100 * 124 95/100 =
= 7/100 * 12495/100 =
= 87465/10000 =
= 8,7465

As far as we talk about money, we can round it to the nearest cent:

8.7465 ≈ 8.75

So we have $124.95 (original price) + $8.75 (tax) + $10 (charge for shipping).

$124.95 + $8.75 + $10 = $133.70 + $10 = $143.70

Patel paid $143.70.

C. i believe it is (5×(-20))+(100×(0.7))
