Represent real-world problems writea real-world situation that can berepresented by 15c 17.50. thensolve the equation and describe whatyour answer represents for the problemsituation. its do tomorrow

To repeat, we need this:
15+c=17.50.

let's imagine a person who wants to save up for a book that costs 17.50. This person has already saved 15 dollars. how much more does he or she still need to save?
So now we solve:
15+c=17.50
subtract 15 from both sides
15+c=17.50
15-15+c=17.50-15
c=2.5

so the person needs to save 2.5 dollars more.

Idon't know the answer
