Question

Ella bought a salad dressing for $8 and three tomatoes for t dollars each. a. Write an expression for the total amount Ella spent. b. If each tomato cost $2, how much did Ella spend?

Answer 1

Given:

• Cost of salad dressing is 8 $
• Cost of tomato is t $ and 3 tomatoes were bought.

To find:

1. Expression for total amount spent
2. If cost of tomato is $2, how much did Ella spend.

Solution:

• Lets say Cost of salad is $x and tomato is t$.
• Lets say n tomatoes were bought.
• So total amount spent (m) = cost of dressing + (No. of tomatoes * Cost of tomatoes)
• Expression becomes,
• m = x + n*y
• Now, cost of salad dressing is $8. so x = $8
• Cost of one tomato = y = $2
• Number of tomatoes = n = 3
• Substituting in equation, we get total amount spent,
• m = 8 + 3 * 2
• m = 8 + 6
• m = 14$
• Total amount spent = 14$

Answer:

1. The expression for total amount spent is m = x + n*y.
2. Total amount spent by Ella is $14.
