Answer:
48 liters
Step-by-step explanation:
First container = x
Second container has twice as much oil.
Second container = 2x
13 liters of oil was used from first container.
x - 13
7 liters of oil was used from the second container.
2x - 7
Second container has 3 times more oil than the first one.
2x - 7 = 3(x - 13)
x - 7 = 3(x - 13)
x - 7 = 3x - 39
2x = 32
x = 16
First container = 16 liters
second container = 16 x 2 = 32 liters
Total = 16 + 32 = 48 liters

Answer:
a = 600
b = 1200
Step-by-step explanation:
a =,
600 = 100%
60 = 10%
with simple interest you add the original ten percent each time so,
600+60+60+60+60+60 etc....
or
you could do 600 x 1.1¹⁰
they both work the same
b = 600 + (ans of a)
