Question

A clown sells large balloon animals for $25 each. Small balloon animals sell for $10 each. Jordan is buying 2 large balloon animals and x small balloon animals. Let y represent the total cost Jordan must pay in dollars. Part 1: Write an equation in slope-intercept form to model this description. Part 2: What is Jordan’s total cost if she purchases 4 small balloon animals? Show your work.

Answer 1

Answer: Part 1: y =10x+50

Part 2: Jordan’s total cost = $90

Explanation:

Given: Price of each large balloon = $25

Price of each small balloon = $10

Price of 2 large balloons = 2 (Price of each large balloon)

= $2 (25)

= $50

Part 1: Total cost = (Number of small balloons)(Price of each small balloon) + (Number of large balloons)(Price of each large balloon)

Let x = Number if small balloons , y= total cost Jordan must pay in dollars.

Then, y= (x)(10)+(2)(25)

⇒ y =10x+50

Part 2: If she purchases 4 small balloon animals, put x=4

Then, y= 10(4)+50=40+50= 90

i.e. Jordan’s total cost = $90
