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
Maybe the answer is 1 x 3
I can tell you .5 equal 30min wait i will solve the rest start with this info
Answer:
Suzette makes more
Step-by-step explanation:
Suzette = 30000 x 1.085^15 = 101992.28
Bridgett = 8.5/100 = 0.85, 0.85 x 30000 = 2550, then use simple interest formula (P(1+rt) , 30000 + (15x2550) = 68250
Suzette - 101992.28 - compound interest
Bridgett - 68250 - simple interest
