Answer:
The first increase was of 60%.
Step-by-step explanation:
The initial value of the product is x.
The first increase was of y.
The second increase is of 25%, that is, 1.25.
The final price was double the original, so 2x.
This situation can be modeled by the following equation:
We want to find y.
Simplifying by x
After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.
Elvira (e) is 5 years older than Morton (m)
e = m + 5
Morton (m) is twice as old as Michelle (c)
m = 2c
The combined total of their ages is 85
e + m + c = 85
We want m at the end so let's write everything in terms of m.
e = m + 5
c = m/2
85 = e + m + c = m+5 + m + m/2 = 5 + (5/2) m
m = (2/5) (85 - 5) = 32
Answer: 32 years old
Check:
That makes Elvira 37 and Michele 16, total 32+37+16=85, good
