Frank borrowed $7 a week from a friend for 8 weeks. Which integer represents how
much money Frank owes his friend?

The correct integer is -56

Step-by-step explanation:

If Frank borrowed $7 per week for 8 weeks, then the equation we will need to solve is 7 x 8 = m. ("m" will stand for the amount of money Frank owes his friend). We will have to multiply the amount of money per week by the number of weeks which will end up giving us a total of $56 that Frank owes his friend. But since Frank owes his friend money, he is going to lose the money which means it has to be negative which will give us an integer of -56
