Q. A manufacturing plant earned $80 \$ 80 per man-hour of labor when it opened. Each year, the plant earns an additional 5% 5 \% per man-hour.\newlineWrite a function that gives the amount A(t) A(t) that the plant earns per man-hour t t years after it opens.\newlineA(t)= A(t)=
  1. Identify initial amount and increase rate: Identify the initial amount earned per man-hour and the annual increase rate.\newlineThe initial amount earned per man-hour is $80\$80. The annual increase rate is 5%5\% or 0.050.05 in decimal form.
  2. Write function for amount earned per man-hour: Write the function for the amount earned per man-hour after tt years.\newlineThe amount earned per man-hour after tt years can be represented by an exponential growth function because the earnings increase by a constant percentage each year.\newlineThe general form of an exponential growth function is A(t)=A0×(1+r)tA(t) = A_0 \times (1 + r)^t, where A0A_0 is the initial amount, rr is the growth rate, and tt is the time in years.
  3. Substitute values into exponential growth function: Substitute the given values into the exponential growth function.\newlineUsing the initial amount A0=$80A_0 = \$80 and the growth rate r=0.05r = 0.05, we get the function A(t)=80×(1+0.05)tA(t) = 80 \times (1 + 0.05)^t.
  4. Simplify the function: Simplify the function.\newlineThe function simplifies to A(t)=80×(1.05)tA(t) = 80 \times (1.05)^t. This function represents the amount the plant earns per man-hour tt years after it opens.
