Answer:
32.40
Step-by-step explanation:
The shirts were 40% of the regular price
The sale price of 1 shirt was
18*40% = sale price
18*.40 =7.20
He bought 3 shirts, so multiply by 3
3 * 7.2 =21.60
He paid 21.60
The price he would have paid without the discount is
18*3 = 54
The savings is
54- 21.60 =32.40
What we need to do with this problem is multiply the amount the computer costs ($350) by the tax rate (6%). To do this, we first need to convert the percentage to a decimal, so we divide the 6 given by 100, leaving us with .06. Next, we need to multiply the $350 by the .06, giving us $21 as the amount we should be paying for sales tax. So your answer should be 2) $21.00!
Answer:
$468.75
Step-by-step explanation:
52 packages = $195
125 packages = ?
125 x (195/52)
= 125 x 3.75
= 468.75
25/28
is in it's lowest form, as it cannot be reduced anymore.
25/28 = 0.8928571

Answer: 7 π r² + π r³
Explanation:
1) The general formula for the volumen, V, of a cylinder with radius r and height h is:
V = π r² h
2) Now you have the condition that the height is 7 inches greater than the radius, that is:
h = 7 + r
3) Replace h with its expression
V = π r² (7 + r)
4) Expand the product (use distributive property):
V = π (7r²) + π r³ = 7 π r² + π r³
Answer: 7 π r² + π r³
