Answer:
a. $5.43
b. $141.25
c. $8.75
Step-by-step explanation:
First you find the total amount you it cost for all the items
$135.82 + 4% = $141.25
You give three $50 dollar bills
50 * 3 = 150
$150 is the amount you give
--------------------------------------
141.25 - 135.82 = 5.43
$5.43 is the amount of the sale price
---------------------------------------
To find the amount is cost for all the items you add the sales tax + the original price
$135.82 + 4% = $141.25
$141.25 is the amount including the tax
---------------------------------------
Subtract
150 - 141.25 = 8.75
So you will get $8.75 back
Volume of cube = 1/3 * pi * r^2 * h
83.74 = 1/3 x 3.14 x r^2 x 5 = 5.233r^2
r^2 = 83.74/5.233 = 16
r = sqrt(16) = 4
Therefore, d = 2(4) = 8 inches.
The account A has amount $600 and B has $1600.
<u>Step-by-step explanation:</u>
The given equations are:
a+b=2200 ⇒1
0.03a+0.05b=98 or +⇒2
Change the first equation by isolating a,
a = 2200-b. ⇒3
Apply equation 3 in 2,
+=98.
66- +=98.
66+ = 98.
6600+2b=9800.
2b=9800-6600.
2b=3200.
b=1600.
Substitute b value in equation 3
a=2200-1600.
a=600.
