I (will / will not) _____________ have enough money because

Answer 1

A. To write an equation we need to determine what the variables are going to be which in this case is m (money) and d (days). 

 

m(0)= 140 because you start with 140 dollars and have not spent any money yet.

 

We also know that you will spend $24 a day (which will make it negative). So the variable d will be multiplied by 24 to get -24d. So the equation looks like this:

 

m= 140-24d

 

B. From here it is just plugging the 5 into the equation:

 

m= 140- 24*5= 140-120= 20

 

From there you compare how much money you have left over to the amount of the sweater and give the reasoning.
