The gemme decided to give their children a weekly allowance that is directly proportional to each childs age. Their 6-old daughter receives an allowance of $4.50. What is their their 11-year-old son's allowance

Answer provided by our tutors

a = ky

where y is age

a is allowance

for 6 old daughter

y = 6 and a = 4.50

therefore

4.50 = 6k

k = 0.75

now for 11years old son

y = 11

a = (0.75)(11)

a = 8.25 $
