the youngs decided to give their children a weekly allowance that is directly proportional to a child's age their six year old daughter receives an allowance or 4.50 what is there 11 year old son's allowance each week

daughter's age determines that for each year the allowance increases by 0.75

Son's Allowance = 8.25

Step-by-step explanation:

The general equation is

Allowance = Age * a base amount.

So the six year old has givens

Allowance = 4.50

Age = 6

Base amount = x

4.50 = 6 * x Divide by 6

4.50 / 6 = 6 x/6 Do the division

0.75 = x

So every year is worth 75 cents.

Eleven year Old

Allowance = ? = y

Base amount = 0.75

age = 11

Allowance = Age * base Amount

y = 11 * 0.75

y = 8.25
