Problema Solution
Tessa has two babysitting jobs this summer. She has worked out a schedule with each family to fit their individual needs. Each week, Tessa babysits 5 hours less for the first family than she does for the second family. On average, she babysits a total of 33 hours per week. How many hours does she babysit for each family?
Answer provided by our tutors
let
x = the hours Tessa babysits for the first family
y = the hours Tessa babysits for the second family
Tessa babysits 5 hours less for the first family than she does for the second family
x = y - 5
On average, she babysits a total of 33 hours per week
x + y = 33
by solving the system of equations
x = y - 5
x + y = 33
we find
x = 14 hours
y = 19 hours
