Question

Ginny is saving for a pair of boots. They cost about $44, including tax. She already has saved $12. How would I write am equation about how much money she needs to save. M= amount of money

Answer 1

44 = 12 + M

Explanation:

Start with your final amount that everything else is going to equal

44 =

Then, add the $12 that is already saved to the other side\

44 = 12

But, that equation is not true yet, so we have to add the amount of money that she still needs to save

44 = 12 + M

That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
