Question

Suzy went to a department store and bought 3 pairs of shoes. The first pair of shoes were not too expensive, but the second pair was twice as much as the first pair. The third pair of shoes were $5 more than the first pair. Pick an equation that fits the following situation where T represents the total cost.

a) 3x + 5 = T
b) 4x - 5 = T
c) x + 2x(x + 5) = T
d) 4x + 5 = T

Answer 1

The equation that fits the situation is d) 4x + 5 = T.

Step-by-step explanation:

The equation that fits the given situation is d) 4x + 5 = T. Let's break down the information given in the question:

1. The first pair of shoes were not too expensive, so the cost can be represented as x.
2. The second pair of shoes was twice as much as the first pair, so its cost is 2x.
3. The third pair of shoes were $5 more than the first pair, so its cost is x + 5.
4. Since Suzy bought 3 pairs of shoes, the total cost is the sum of the costs of each pair: x + 2x + (x + 5) = 4x + 5.

Therefore, the equation that represents the situation is 4x + 5 = T.
