6. Sue goes to the bakery and purchases cupcakes and cookies for a picnic. She needs to serve 36 people. Cupcakes cost $2.50 eac
ruslelena [56]

Answer:the number of cupcakes that Sue purchased is 12

Step-by-step explanation:

Let x represent the number of cupcakes that Sue purchased at the bakery.

Let y represent the number of cookies that Sue purchased at the bakery.

She needs to serve 36 people. This means she would purchase a total of 36 people. Therefore,

x + y = 36

Cupcakes cost $2.50 each, cookies cost $1.00 each. She spends $54.00. This means that

2.5x + y = 54 - - - - - - - - - 1

Substituting x = 36 - y into equation 1, it becomes

2.5(36 - y) + y = 54

90 - 2.5y + y = 54

- 2.5y + y = 54 - 90

- 1.5y = - 36

y = - 36/ - 1.5

y = =24

x = 36 - y = 36 - 24 = 12

5 + 5

= 2 + 2 + 2 + 2 + 2

= 4 + 4 + 2

= 8 + 2

Thus, 10 ÷ 5 does equal 2


Therefore, your answer is: 2
