Question
Callie entered an art contest in second grade and won a $1,000 scholarship. The money was invested in an account paying a 9% interest rate compounded annually. The situation can be modeled by the equation a(t)=1,000(1.09)t
, where a is the amount in the account after t years. If Callie uses the scholarship 10 years later, determine which graph accurately displays the situation.(1 point)

An increasing curve with an arrow at the end is plotted in the first quadrant of a coordinate plane. The x-axis ranges from 0 to 5 in increments of 1 and the y-axis ranges from 0 to 2000 in increments of 500.

The second graph (x-axis 0–14, y-axis 0–3500 with points (0,1000), (8,1990), (12,2810), (14,3340)).

Reason: a(t)=1000(1.09)^t is exponential growth (increasing). After 10 years a(10) ≈ 1000(1.09)^10 ≈ 2367, which fits the scale and points shown on that graph.
