Problem
Write an equation for the linear function and use it to answer the given question. The price of a particular model car is \( \$ 12,949 \) today and rises with time at a constant rate of \( \$ 1363 \) year. row much will a new car cost in 4.5 years? \( p=12,949 t-1363 ; \$ 56,907,50 \) \( p=12,949+1363 t ; \$ 19,082.50 \) \( p=12,949-1363 t ; \$ 6815.50 \) \( p=1363+12,949 t ; \$ 59,633.50 \)
Solution
Step 1 ：p=12949+1363t
Step 2 ：p(4.5)=12949+1363(4.5)
Step 3 ：p(4.5)=19082.50
