Answer:
with what
Step-by-step explanation:
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.

Answer:
sqrt(5)/29
Step-by-step explanation:
1/(5 + 3sqrt(5))
= 1/(5 + 3sqrt(5)) x sqrt(5)/sqrt(5)
= sqrt(5)/(5 + 3 x 8)
= sqrt(5)/ 29
