Wants to have a smoothie for breakfast every day and plans on a total of 6 cups of smoothies made from frozen fruit puree and yogurt. Knowing that fruit puree costs $2.00 per cup and yogurt costs $3 per cup, she budgets $14.00 for the ingredients. Which system could Alyssa’s roommate Marni use to find x, the number of cups of fruit puree, and y, the number of cups of yogurt, Alyssa plans to buy?
x + y = 6
2x + 3y = 14
x + y = 6
3x + 2y = 14
6x + 2y = 14
2x + 3y = 6
x + y = 14
2x + 3y = 6
