Answer:
80,000 + 1.04 to the forth power
Step-by-step explanation:
First term is initial number
Second term is one plus the percent as a decimal (if it’s an increase)
Then to the power of 4 assuming that there are 4 year in between 2016 and this year, 2020
(1 2/3) / 50 = x/60
cross multiply
50x = 60 * 5/3
50x = 100
x = 100/50
x =her walking pace is 2 miles per hr
So 1000987 in 3 years or 1000987:3 or i like to put it as 1000987:3
we notice that 6 is 2 times of 3 so we just multiply 1000987:3 by 2 and get 2001974:6
2001974 in 6 years
