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
If you put 4 over 20 and did a ratio to x over 100 it would be 20%
Answer:
y=9/7x - (-29/7)
Step-by-step explanation:
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.
