Kayla is given a monthly allowance. she puts 40% of the money directly into her savings account. she spends $15 at the movies with her friends. at the end of the month she has $3 left . how much is her monthly allowance ?

$45

Step-by-step explanation:

Let the monthly allowance be $ x.

Savings = 40% of $x = $0.4x

Remaining = $x - $0.4x = $0.6x

She spends $15 and at the end of the month she has $3 left, so the values should be added.

$0.6x + $15 + $3 = x

- 0.4x = -18

x = 18/0.4

x = $45

What did we take as x? The Monthly allowance? So $ 45 is the monthly allowance

answer: -8.2562234e+13
