A conservation group pledges to plant trees by adopting areas throughout a region starting in 2020. The function A(t)=10+5t models the number of areas A the group will adopt t
years after 2020. The group also pledges that the number of trees in each area P models the function P(t)=25+4t , where t is the number of years after 2020. Explain whether the number of trees that are planted by the group in the year 2030 is 23,200 .
A) The number of trees planted by the group is 23,200 because the value of t is 30 in 2030. Multiplying A(30) by P(30) results in 23,200.
B) The number of trees planted by the group is not 23,200 because the value of t
is 1 in 2030. Multiplying A(1) by P(1) results in 435
C) The number of trees planted by the group is not 23,200 because the value of t is 10 in 2030. Adding A(10) by P(10) results in 125
D) The number of trees planted by the group is not 23,200 because the value of t is 10 in 2030. Multiplying A(10) by P(10) results in 3,900.
