The <em>correct answer</em> is:

He paid the correct amount.

Explanation:

First we find the subtotal of Manny's items:

32.65+3(14.89)+39.99 = 32.65+44.67+39.99 = 117.31

Next, we calculate the discount. If he gets 10% off, this means he pays 100%-10% = 90% of the total. 90% = 90/100 = 0.9:

0.9(117.31) = 105.579

Next we calculate the tax. Since tax is 8%, this means he pays 100% of his subtotal after discount plus the 8% tax; 100%+8% = 108%; 108% = 108/100 = 1.08:

1.08(105.579) = 114.02532 ≈ 114.03

Since this is what he paid, he paid the correct amount.

A basketball has a diameter of 9.5 inches what is the volume of the basketball using 3.14 for pi.
Step2247 [10]

Answer:

  448.69 in^3

Step-by-step explanation:

The volume of a sphere is given by the formula ...

  V = (4/3)πr^3

We want to use diameter, so we can substitute r = d/2 into the formula:

  V = (4/3)π(d/2)^3 = (4/(3·8))πd^3

  V = (π/6)d^3

For the given numbers, ...

  V = (3.14/6)(9.5^3) ≈ 448.69 in^3 . . . . volume of a basketball

mestny [16]
The unit rate for the 1st one is: $0.19 / ounce

The unit rate for the 2nd one is: $0.16 / ounce

The 36 ounce box would be the better buy because it is less per ounce than the 24 ounce box
