Question

a. $36.25

b. $71.05

c.. $30.45

d. $8.67

e. $20.30

Answer 1

50.75 = 1.4x

x= 36.25

36.25 (100% + 40%) = 50.75

36.25 + 14.50 = 50.75

Answer 2

$50.75/1.40=$36.26

a.

Answer 3

The equation needed to solve would be set up like this:

1.40x = 50.75

Here is why:

The cost of the book is increase by 40%. The decimal representation of the 40% is 0.40. 100% is represented as 1.00. If you want to calculate what a new amount is of a value that is increased by a certain percent, then you just multiply it by the total cost plus the percentage increase. For example, 100% of the cost of the book + 40% increase equals 140% or 1.40, then multiple it by the actual cost of the book: 1.40x (since in this case the original cost of the book is unknown, as represented by x). Then, set it equal to the bookstore price: 1.40x = $50.75

Divide both sides by 1.40 and you have your answer.

x = $50.75/1.4 or $36.25

Answer 4

140% = 1.4

$ 50.75 / 1.4 = $ 36.25
