Answer: it will take 25 months
Step-by-step explanation:
Let x represent the number of months that it will take for the cost of both plans to be the same.
Cell phone Plan A costs $70 per month and comes with a free $500 phone. This means that the total cost of x months with plan A would be
70 × x = $70x
Cell phone plan B costs 50 per month but does not come with a phone. If you buy the 500 phone and choose plan B, then the total cost of x months with plan B would be
500 + 50 × x = 500 + 50x
To determine the number of months until your cost is the same as Plan A's, we would equate both costs. It becomes
70x = 500 + 50x
70x - 50x = 500
20x = 500
x = 500/20 =25
Answer:
15 years
Step-by-step explanation:
Given data
P=$1,000
R=8%
A= $2200
I= A-P
I=2200-1000
I=$1200
Applying the formula
I=PRT/100
1200=1000*8*T/100
cross multiply
1200*100= 8000T
120000= 8000T
divide both sides by 8000
T=120000/8000
T=15 years
Hence the time is 15 years
