A parent deposits $2000 into their child's bank account. The account earns 4% interest each year. Write an explicit function that represents the situation. *
A(t) = 20000.04)
A (t) = 200001.04)-1
A(1) = 2000(4)
A (t) = 2000 + 41

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
