Question

In a coffee shop, the average drink is currently $4.50 while the average pastry is $2.25. You've made a total of $5,250 today. Write an equation to model the breakdown of your sales between drinks and pastries.

Answer 1

`4.50x+2.25y=5,250` where
`x` denotes number of drinks and
`y` denotes number of pastries.

Explanation:

Let
`x` denotes number of drinks and
`y` denotes number of pastries.

Cost of the average drink = $4.50

Cost of the average pastry = $2.25

Total amount = $5,250

Therefore,

`4.50x+2.25y=5,250`
