To find the percent increase, just take 96 and divide by 80. 96/80=1.2 percent as your answerr
The formula for simple interest is given by
![I= \frac{PRT}{100}](https://tex.z-dn.net/?f=I%3D%20%5Cfrac%7BPRT%7D%7B100%7D%20)
where P is the principal, R is the rate and T is the time.
Let the additional interest Benson pays each year be P, then
![\frac{P\times2\times1}{100} =180 \\ \\ \Rightarrow2P=180\times100=18000 \\ \\ \Rightarrow \frac{18000}{2} =9000](https://tex.z-dn.net/?f=%20%5Cfrac%7BP%5Ctimes2%5Ctimes1%7D%7B100%7D%20%3D180%20%5C%5C%20%20%5C%5C%20%5CRightarrow2P%3D180%5Ctimes100%3D18000%20%5C%5C%20%20%5C%5C%20%5CRightarrow%20%5Cfrac%7B18000%7D%7B2%7D%20%3D9000)
Therefore, the additional interest Benson pays each month is given by
Velocity=-32t+440
At maximum height, v=0
0=-32t+440
-440=-32t
t=13.75 seconds
Check picture for working out
X= # of sodas sold
x - 42 = # of hot dogs sold
x+x-42=202
2x = 244
x=122
122 sodas and 80 hot dogs
