High School

I had [tex]\$147[/tex]. Then I spent [tex]\$42[/tex] on sneakers. After that, I earned [tex]\$45[/tex] by winning a race in my new sneakers.

Which equation can I use to find out how much money [tex](m)[/tex] I have now?

Choose one answer:

A. [tex]147 + 42 + 45 = m[/tex]

B. [tex]147 + 42 - 45 = m[/tex]

C. [tex]147 - 42 + 45 = m[/tex]

Answer :

Sure! Let's solve this problem step by step.

1. Start with the initial amount of money: You had [tex]$147 to begin with.

2. Subtract the money spent: You spent $[/tex]42 on sneakers. To find out how much money is left after buying the sneakers, subtract 42 from 147.
[tex]\[
147 - 42
\][/tex]

3. Add the money earned: After spending on the sneakers, you earned [tex]$45 by winning a race. To include this money, add 45 to the remaining amount after buying the sneakers.
\[
(147 - 42) + 45
\]

4. Calculate step by step:
- First, solve the subtraction:
\[
147 - 42 = 105
\]
- Then, solve the addition:
\[
105 + 45 = 150
\]

So, the amount of money you have now is $[/tex]150. The correct equation to describe this situation is option (C): [tex]\(147 - 42 + 45 = m\)[/tex].
