Let the price of the computer = X
Store A is selling it for 25% off, so they are selling it for 75% of the original price, so you have 0.75X
Store B is selling it for 180 less the original price, so you have X - 180
Now set both equations to equal and solve for x:
0.75x = X-180
Subtract 1X from each side:
-0.25x = -180
Divide both sides by -0.25:
x = -180 / -0.25
X = 720
The original price is $720
check:
720 x 0.25 = 180
Answer:
Yes.
Step-by-step explanation:
The radius in the formula for a volume of a cylinder is squared so yes the volume would be higher, but it depends on the height as well.

1) The sales tax for the toilet paper is $0.17.
2) The price of the coat is $43.63 and the sales tax is $2.24.
Step-by-step explanation:
1) Let the cost of the toilet paper be 'a'
Sales tax = 5.125%
Total cost = $3.50
Total cost = price+ 5.125% of price
3.50 = a + (5.125 x a/100)
3.50 = (100a + 5.125a) /100
350 = 105.125a
a = 350/105.125
a = $3.33
Sales tax = 3.50 - 3.33
= $0.17
The sales tax for the toilet paper is $0.17.
2)let the price of the coat be 'a'
cost of the coat = $45.87
Cost = a + 5.125% a
45.87 = a + (5.125/100) a
45.87 = ( 100a + 5.125a) /100
4587 = 105.125a
a = 4587/105.125
a = $43.63
Sales tax = 45.87 - 43.63
= $2.24
The price of the coat is $43.63 and the sales tax is $2.24
The formula is n/2(a1+an). n is the number of terms. a1 is the first value in the sequence and an is the value of the sequence at the nth term
