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 not 23, 200 because the value of t is 10 in 2030. Adding A (10) by P (10) results in 125.
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. Multiplying A (10) by P (10) results in 3, 900.
D.) 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.
