R=rita's age
m=mother's age
g=grandmother's age
mother is 4 times as old as rita
m=4r
grandmother is 2 times as old as mother
g=2m
sum is 104
r+m+g=104
subsitute 4r for m and 2m for g
r+4r+2m=104
subsitute 4r for m
r+4r+2(4r)=104
r+4r+8r=104
13r=104
divide both sides by 13
r=8
4r=m=32
8r=2m=g=64
rita is 8
mother is 32
grandmother is 64
Given:
principal 15,000
term 9 years
rate 8.5%
Interest = Principal * Interest Rate * Term
I = 15,000 * 8.5% * 9
I = 11,475
Total = 15,000 + 11,475 = 26,475 on date of maturity
Interest = 15,000 * 8.5% * 2
I = 2,550
Total = 15,000 + 2,550 = 17,550
amount withdrawn = 4,000
Penalty = 4,000 * 8.5 % * 6/12
P = 170
Net amount = 17,550 - 4,000 - 170 = 13,380
I = 13,380 * 8.5% * (8-2)
I = 6,823.80
Total = 13,380 + 6,823.80 = 20,203.80 total amount on maturity.
Answer:
$220
Step-by-step explanation:
To find for 1 week
$20.00÷2= $10
For 22 weeks
22×10=220
Step-by-step explanation:
Hey there!
Given;
[A = 1/2b*h]
Divide both sides by 'h'.
A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].
Multiply '2' and 'A'.
A*2/h = b
b = 2A/h.
