melanie spent half of her allowance going to the movies. she washed the family car and earned 6 dollars.what is her weekly allow
geniusboy [140]

Her weekly allowance is $20

Step-by-step explanation:

Let her weekly allowance be 'a'

Given that,

She spent half of the allowance (a/2)

So,

Money left with her = (a/2)

She earned $6 by washing the car

She has $16 at the end.

So,

(a/2) + 6 = 16

(a/2) = 16 - 6

(a/2) = 10

a = 10 x 2

a = 20

So, her weekly allowance is $20

X is 110% of 10, y% of 50 is 3.5
podryga [215]

Answer:

Step-by-step explanation:

If x is 110% of 10, then x = 1.10(10) = 11.

***********************************************

If y percent of 50 is 3.5, then:

y

------- (50) = 3.5

100

Multiplying both sides by 100, we get 50y = 350, which yields:

       350

y = --------- = 7

        50

This y = 7 is a percentage.
