Question

Jake bakes cakes for a fundrasier, he spent $50 on supplies and sells each cake for $25. He wants to make more than $100 for the fundraiser, as well as pay for the supplies. What is the number of cakes (c) jake needs to sell to reach his goal?

1. Write the inequality
2. Use inverse operations to solve,add, then divide.
3. Graph the solution in a number line.

Answer 1

Let number of cakes be c

The expression for Jake's goal is

• 25c>50+100
• 25c>150
• c>150/25
• c>6

Put a open dot at 6 and draw a line rightwards

Answer 2

• c > 6

Explanation:

Each cake sells for $25, the number of cakes is c.

Jakes goal is reflected below:

• 25c > 100 + 50

Solve for c:

• 25c > 150
• c > 150/25
• c > 6

The graph includes the number line from the point 6 (open circle) to the right
