Set up a proportion
2/3= 120/x
2*60=120
3*60=180
x=180
Final answer: $180
So your starting amount is 5. Your equation will start like this:
5+
Now 45 dollars a week. So no matter how many weeks you are going to multiply it by 45. So you add that in and you have an equation that looks like this:
5+45x
X stands for the weeks. Then finish it off with your equals:
5+45x=y
Y is the total amount of money.
The Equation will be.
5+45x=y
Part 2:
The equation is set up on weeks so you need to find out how many weeks 28 days is.
28/7=4
Now that you know that you can substitute 4 for x.
5+45*4=y
5+180=y
185=y
He will have 185 dollars in his bank. <span />
