Eric and Sarah both have lemonade stands. The graph below represents how many cupsof lemonade Eric sells per day. The equation represents the rate at which Sarahmakes lemonade. Who sold more cups of lemonade in 5 days?

Answer 1

The graph indicates that Eric sells 60 cups of lemonade in 5 days.

Substituting x = 5 in the equation of Sarah, we get:

y = 10x

y = 10*5

y = 50

That is, Sarah sells 50 cups of lemonade in 5 days.

Then, Eric sells more cups.
