Question

Working her way through school, Liz works two part-time jobs for a total of 30 hours a week. Job A pays $5.90 per hour, and Job B pays $7.50 per hour. How many

ours did she work at each job the week that she made $207.40? (Round to two decimal places if necessary.)

Answer 1

$5.90x + $7.50(30 - x) = $207.40

$225.00 - $1.60x = $207.40

$1.60x = $17.60

x = 11 hours at Job A

30 - 11 = 19 hours at Job B
