A jumbo smoothie costs $4.95. Two jumbo smoothies and one medium smoothie cost $0.15 more than 4 medium smoothies. How much does a medium smoothie cost?

a medium smoothie cost $3.25

Step-by-step explanation:

j = 4.95 which is the cost of one jumbo

equation from word problem

2j + m = 4m + 0.15

subtract m from both sides

also subtract 0.15 from both sides

2j - 0.15 = 3m

substitute j

2(4.95) - 0.15 = 3m

9.75 = 3m

m = 3.25 or $3.25
