Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155

Answers

Answer:

A. 0.40x - 15=155

Step-by-step explanation:

40% can be written as 0.40

x = total money earned

-15 from that total

The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155

Let :

monthly allowance = X

Designer bag purchase = 40% of X = 0.4X

Donation to charity = $15

Total amount left = $155

Percentage left after bag purchase :

1 - 0.4X = 0.6X

0.6X - charity = amount left

Therefore, the required expression is 0.6X - 15 = 155
