Step-by-step explanation:
to find the amount ty earns for each job multply his hourly rate by the number of hurs he works doing each job. the find the total
Answer:
B.
Step-by-step explanation:
They paid 111.75 for there months that means they minus 5.50 dollars every month which means a total of of 16.5 for three months. So you need use 111.75 plus the credit 16.5 dollars for three months 111.75+16.5=128.25 and than you divide them by 3 for three months so they pay 42.75 per month before the credit
Answer: 15.75
Step-by-step explanation: To calculate, we do 45 x 35 / 100 which will equal 15.75
