the total cost of a pizza and 3 drinks is $19. the price of the pizza is $10 and each drink is the same price, d. which model represents the situation?
Answer
Explanation:
Step1: Analyze the cost components
The total cost is the sum of the pizza - price and the cost of 3 drinks. The pizza price is $10 and each drink costs $d$, so the cost of 3 drinks is $3d$. The total cost is $10 + 3d$, and it is given as $19$.
Step2: Match with the models
We need a model that shows a value of 10 for the pizza and three values of $d$ for the three drinks, all adding up to 19.
Answer:
The fourth model (the one with 10, d, d, d on the top - row and 19 on the bottom - row) represents the situation.
