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 $
