Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 8% each week. The following function represents the weekly weed growth: f(x) = 86(1.08)x. Rewrite the function to show how quickly the weeds grow each day.

Question

f(x) = 86(1.08)7x; grows approximately at a rate of 5.6% daily

f(x) = 86(1.087)x; grows approximately at a rate of 0.56% daily

f(x) = 86(1.01)x; grows approximately at a rate of 0.1% daily

f(x) = 86(1.01)7x; grows approximately at a rate of 1% daily

Answer 1

multiply by 1.08 every week
but we are doing per day
1.08 = x^7
7 log x = log 1.08
log x = 0.004775
x = 1.011
so
1.1 percent daily
