A store sells gift cards in preset amounts. You can purchase gift cards for $10 or $15. You have spent $340 on gift cards. Write an equation in standard form to
represent this situation. What are three combinations of gift cards you could have purchased?
Let x be the number of gift cards for $10, and let y be the number of gift cards for $15. Write an equation in standard form to represent this situation. Choose the
correct equation below.
O A. 10x +15y = 340
O B. 10x - 340 = 15y
O C. 10y +15x = 340
O D. 10y - 15x = 340
What are three combinations of gift cards you could have purchased?
O A. 22 gift cards for $10 and 0 gift cards for $15; 4 gift cards for $15 and 20 gift cards for $10; 16 gift cards for $15 and 12 gift cards for $10
O B. 1 gift card for $10 and 22 gift cards for $15; 4 gift cards for $10 and 20 gift cards for $15; 16 gift cards for $10 and 12 gift cards for $15
O C. 22 gift cards for $10 and 1 gift card for $15; 4 gift cards for $10 and 20 gift cards for $15; 16 gift cards for $10 and 12 gift cards for $15
O D. O gift cards for $10 and 22 gift cards for $15; 4 gift cards for $10 and 20 gift cards for $15; 16 gift cards for $15 and 12 gift cards for $10
