Upon renewing your cell phone, you have two options:
Margaret [11]

first put both options into equation format. option 1: 360+75m and option 2: 24(30). solve the easier problem first which is 24 multiplied by 30 which equals 720. so now you know what should be on the side of the equal sign so that they both have eqaul solutions. 360+75m =720. subtract 360 from both sides so that equation turns to 75m=360, then divide both sides by 75 and get 4.8. it would take 4.8 months

Naya [18.7K]

The balance in dollars and cents in Yolanda's account at the end of 4 years is $5,355.29

What is the future value of an ordinary?

An ordinary annuity is the one where the monthly deposit occurs at the end of each month rather than at the beginning of the months such its future value based on 5.5% annual interest rate can be determined thus:

FV=PMT*(1+r)^N-1/r

FV=balance in dollars and cents in Yolanda's account at the end of 4 years=unknown

PMT=monthly deposit=$100

r=monthly interest rate=5.5%/12=0.00458333333333333

N=number of monthly deposits in 4 years=4*12=48

FV=$100*(1+0.00458333333333333)^48-1/0.00458333333333333

FV=$5,355.29
