write and solve a real world problem that can be represented by the expression (-3)(5)+10.

Question

I don't know what to do. Can you help me?

Answer 1

Hi, Sophie. 

So, let's say your parents give you $10 a week for allowance.

So, let's say that last week you spent $3/day for smoothies everyday after school (Mon - Fri). Then, on Friday they paid you your allowance again. So, you could say that last week your expenses were:

(-3)(5) + 10 = -15 + 10 = -5 dollars.

So you spent 5 dollars more than you took in. 

 

That is just one example. I hope it helps.
