isolate the variable by dividing each side by factors that don't contain the variable
Answer:
The family spends 41/60 of its income on these items altogether.
Step-by-step explanation:
Given that a family spends 1/10 of it's annual income for housing, 1/4 for food and clothing, 1/5 for general expenses and 2/15 for entertainment, to determine what fractional part of their income is spent on these items altogether the following calculation must be performed:
10, 4, 5, and 15 have a common least multiple at 60.
1/10 = 6/60
1/4 = 15/60
1/5 = 12/60
2/15 = 8/60
6 + 15 + 12 + 8 = 41
Therefore, the family spends 41/60 of its income on these items altogether.
Compound interest formulaAccumulated sum= P(1+r)^twhere P=present valuer=interest per periodt=number of periods
Given
P=48000
i=7% per year
accumulated sum = 121
Need to find t
Apply compound interest formula
121000=48000(1.07)^n
Divide by 48000, and take log on both sides
n*log(1.07)=log(121000/48000)
n=log(121000/48000)/log(1.07)
=13.666 years
Ans. it will take 13.7 years the initial deposit will reach 121000
