Question

Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle. She wrote an equation to find the number of drinks she needs to sell to earn $100.

1.25x 1.49 = 100
What error did Barbara make in writing the equation?
Barbara's equation did not consider the number of water drinks.
Barbara's equation did not consider the number of iced tea drinks.
Barbara's equation did not use the correct price for the iced tea drinks.
Barbara's equation did not use the correct total for sales.

Answer 1

the equation should be:

the cost of water times the number of bottles plus the cost of iced teas times the number of bottle equals 100

1.49 times number of water bottles + 1.25 time number of iced tea bottles = 100

1.49x + 1.25y = 100


The answer is B. she forgot to multiply 1,25 to the number of iced tea bottles/
