Question

before the coffee shop opens, the employees have to bake 40 cookies. We sell cookies for $0.85 and latte's for $3.20. The customer bought some cookies and one latte. If a customer spends $7.45, how many cookies did they buy

Answer 1

The cost of cookie is $0.85 and cost of latte is $ 3.20.

It is given that the latte required by customers is 1.

Let the cookie bought be x .

`x*0.85+1*3.20=7.45`
`0.85x+3.20=7.45`
`0.85x=4.25`
`x=5`

The amount of cookie buy by the customer is 5.
