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
Anna11 [10]

Answer:

x+y = 80\\325x+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:

x+y = 80 ............ 1

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

325 \times x \\325x

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

50 \times y\\50y

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

325x+50y = 6,750 .............. 2

Hence the system of equations represents the situation is:

x+y = 80\\325x+50y = 6, 750
