what is the price of one jolly rancher bag and what is the price for one mars minis bag.

Question

Lucia is throwing a party for her niece and can buy 1 bag of jolly ranchers and two bags of mars minis for $28.96. Preparing for Halloween she knows she can get two bags of jolly ranchers and one bag of mars minis for $27.90. What is the price for a single bag of jolly ranchers? What is the price for a single bag of mars minis?

Answer 1

Let x be price of 1 bag of jolly ranchers

Let y be price of 1 bag of mini Mars

From the question

X + 2y = 28.96 --------- (1)

2x + y = 27.90 ----------(2)

From eqn(1) x = 28.96 - 2y

Substitute x into eqn(2)

2(28.96 - 2y) + y = 27.90

57.92 -4y + y = 27.90

y = 30.02/3

y = $10.006

x = $28.96 - (2 * $10.01)

x = $8.95
