You are buying balloons for a party. a small balloon costs $2. a large balloon costs $3. write an algebraic expression for the cost of x small balloons and y large balloons. then find the total cost for 11 small balloons and 5 large balloons.

Cost for something=how many you are bying times how much each cost

cost for total of small ballons=x times 2 or 2x

cost of total of big ballons=y times 3 or 3y

total is costsmall+costbig=2x+3y

so
TC=2x+3y

if you have 11 small and 5 big (x=11 and y=5), what is TC?
input
TC=2(11)+3(5)
TC=22+15
TC=37

total cost is $37

A: 0.26 would be the answer
