Ralph’s shirt company sells t-shirts for $7.50 each with a flat rate of $10 for shipping. Frank’s t-shirt company sells t-shirts for $10 each with free shipping. A: Write an equation to represent each T-Shirt company.
Ralph's:
Frank's:

B: Solve the system of equations by using the graph.

C: What does the solution mean in the context of the solution?

A: Ralph y = 10 + 7.50x

Frank y = 10x

B: x = 4, y = 40

C: x = 4 means that in order for the companies to make the same amount of money, they have to sell 4 shirts each. When the companies sell 4 shirts (or multiples of 4) they are making the same amount of money.

Step-by-step explanation:

Because both equations are equal to y, set them equal to each other.

10x = 10 + 7.50x

2.5x = 10

x = 4

Plug in x to a y equation.

y = 10(4)

y = 40

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
