1.a.) The recipe for the cake calls for of a cup of cocoa powder. The recipe for icing requires of a cup of sugar. Aunt Heather told the cousins that she has exactly 4 cups of cocoa powder. How many cakes can they make with the amount of cocoa powder they have?
4 = 𝟐 𝟑 𝐱
4( 𝟑 𝟐 ) = ( 𝟐 𝟑 𝐱) ( 𝟑 𝟐 )
𝟏𝟐 𝟐 = 6 = x
They can make 6 cakes with 4 cups of cocoa.

Substitute 39 for the x
into the original equation
3.) Verify that 39 is the solution.
26 = 𝟐 𝟑 (𝟑𝟗)

c. Write an equation that
represents the cost for the
two companies being equal
55h = 65h + 75

15. Page 413 Read for me please…
2. Describe the steps that you will use to solve this equation. Explain your reasoning.
First subtract 55h from both sides of the equal sign.
Next subtract 75 from both sides of the equal sign.
By doing this I will get all the terms with variables
on the right side of the equation and all the constant
terms on the left side of the equation

Nic has $15 to spend. 1. Write an equation to determine how much money Nic will have after playing Dinosaur Tag. Let x represent the number of games and let y represent the amount of money remaining.
y = 15 – 0.75x
2. Use your equation to determine how much money
Nic has remaining after:
a. 4 games
y = 15 – 0.75(4)
y = 15-3

Now Check your answer:
5x = 3x + 18
5x – 3x = 3x – 3x +18
2x = 18
2x ÷ 2 = 18 ÷ 2
x = 9
5x = 3x + 18
5(9) = 3(9) + 18
