Problema Solution
Elenor is working her way through school. She works two jobs totaling 36 hours a week. Job A pays 6.50 an hour. Job B pays 7.00 an hour. How many hours did she work at each job to get a total of 242.50
Answer provided by our tutors
Let 'x' represent the number of hours Elenor works for $6.50 an hour, then (36-x) represents the number of hours she works for $7.00 an hour.
6.50x+7.00(36-x)=242.50
x=19
36-19=17
So Elenor works 19 hours for $6.50 an hour and 17 hours for $7.00 an hour.
