Question

A jumbo smoothie costs $4.95. Two jumbo smoothies and one medium smoothie cost $.15 more than 4 medium smoothies. How much does a medium smoothie cost?

Answer 1

The cost of 1 medium smoothie = $3.38

Explanation:

Cost of 1 jumbo smoothie = $4.95

⇒ Cost 2 Jumbo Smoothies = 2 x $4.95 = $9.9

Let us assume the cost of 1 medium smoothie = m

Now, the Cost of 2 jumbo smoothie and 1 medium smoothie + $0.15

= 4 (cost of 1 medium smoothie)

⇒ $9.9 + m + $0.15 = 4 m

or, 10.15 = 4 m - m

or, 3 m = 10.15

⇒ m = 10.15/3 = 3.38

or, m = 3.38

Hence, the cost of 1 medium smoothie = $3.38
