A tire shop counted 80 invoices at the end of the month. They charge $325 for a set of new tires and $50 for a set of used tires. The total dollar amount of the invoices was $6,750. Let x represent the number of sets of new tires and y represent the number of sets of used tires. Which system of equations represents the situation? a. x+y=80
325z=50y + 6,750
b. z+y=80
325x=-50y+6750
c. x+y=80
325x=-50y-6750
d. x+y=80 -325z=-50y + 6,750

Step-by-step explanation:

Le x represents the set of new tires

Let y be the set of used tires

If a tire shop counted 80 invoices at the end of the month, then the equal that represents the total amount of invoices counted at the end of the month is:

If they charge $325 for a set of new tires, the total amount charged for new tires will be:

If they charge $50 for a set of used tires, the total amount charged for used tires will be:

If the total dollar amount of the invoices was $6,750, then the expression that models the amount generated on tickets will be:

Hence the system of equations represents the situation is:
