Answer:$80.93
Step-by-step explanation: The number of t-shirts that can be made from 48 yards is 60 yards.
The original price of the book is $40.
The cost of 8 computer tables is $1040.
My total bill would be $72.91.
Mrs. Margul's total bill will be $143.75
My total bill after applying the discount of 35% would be $80.93.
If one t-shirt requires 4/5 yards. The number of t-shirts that can be made with 48 yards can be determined by dividing 48 yards by 4/5 yards
48 yards ÷ 4/5 yards
48 x 5 / 4 = 60 shirts
The cost of the book was reduced by 30%. This means that the sales price is 70%(100 - 30%) of the original price.
Let p represent the original price. This equation can be used to represent the information in the question:
70% x p = $28
0.7p = $28
p = $28 / 0.7
p = $40
In order to determine the cost of 8 computer tables, the cost of one computer table has to determined first.
Cost of one computer table = cost of three tables / 3
$390 / 3 = $130
The cost of 8 computer tables = Cost of one computer table x 8
$130 x 8 = $1040
The total bill is the sum of the cell phone bill and the late phone charge
$67.82 + ( 7.5% x $67.82)
$67.82 + (0.075 x $67.82 )
$67.82 + 5.09
= $72.91
Mrs Margul's total bill is the sum of the amount she paid and the cost of her tip.
$125 + ( 15% x $125)
$125 + (0.15 x $125)
$125 + $18.75
= $143.75
Sara's total bill is the cos of the items bought less the amount of the 35%
$124.50 - (35% x $124.50)
$124.50 - (0.35 x $124.50)
$124.50 - $43.58
= $80.93
