Question

Brendan earns $2 for every cup of lemonade he sells. Write an equation that shows the relationship between the number of cups sold x and the earnings y

Answer 1

hi,
Let's name Brendan as "B" for the ease of use...
If B sells 1 cup ---- > the profit $(2*1)
B sells 2 cups ---> profit (2*2)
B sells 3 cups ---> profit(3*2)
B sells x cups ----> profit = y = (x*2)

so the expression u need is
y = 2x

Hope this will help ya!!
