Answer 1

Answer: a) y= 2,170,000(1+0.04)^10
b) 3,212,130 U.S. workers working at home.

Explanation:

Explanation:

initial amount: 2,170,000

rate of growth: 4%, or 0.04

time: 10 years

Using this information we can use the formula y=a(1+r)^t to figure out the answer.

After plugging in the amounts, we end up with the equation: 2,170,000(1+0.04)^10

Now, all that's left is to calculate. The final amount is 3,212,130
