Question

Write an algebraic model for the situation and evaluate it for the given information.

You are going shopping for some new sweaters, t-shirts, and pants. Sweaters (s) cost $28, t-shirts (t) cost $14, and pants (p) cost $23. What algebraic expression models the total cost of clothes that you buy?

Suppose you bought 21 sweaters, 10 t-shirts, and 17 pairs of pants. How much did you spend? 28s + 14r + 23p; $1,099
21s + 10t + 17p; $1,119
28s + 14t + 23p; $1,119
21s + 10t + 17p; $1,099
