Answer:
$4.48
Step-by-step explanation:
First, you have to convert the percentage into a decimal.
12% x 100 = 0.12
Second, you multiply the decimal with the cost of the product before tax.
$4 x 0.12 = $0.48
This number is the amount of money you will have to pay in tax.
Third, you add the tax amount to the original cost of the product to get the total price.
$4 + $0.48 = $4.48
17. 15
18. 8(this one I'm not sure tho what does the right one say)
19. 32
20. 5
y=-x^2-8
Tell me if you need explanation
in hours there would be 156 minutes
so its the second one (1.28 , -3.68)
its (32/25 , -92/25)
which equals to (1.28,-3.68)
