Question

Trisha bought x fifty cents stamps and 3 thirty cent stamps. How much did she spend altogether on the stamps

Answer 1

First, we need to calculate the total cost of the fifty cents stamps. Since Trisha bought x of them, the total cost of the fifty cents stamps would be 0.5x.

Next, we need to calculate the total cost of the thirty cents stamps. Since Trisha bought 3 of them, the total cost of the thirty cents stamps would be 0.3*3 = 0.9.

Finally, we add the total cost of the fifty cents stamps and the thirty cents stamps together to find the total amount Trisha spent on the stamps:

Total cost = 0.5x + 0.9

Therefore, Trisha spent 0.5x + 0.9 on the stamps.
