Trisha bought x fifty cents stamps and 3 thirty cent stamps. How much did she spend altogether on the stamps? But its not 0.5 plus 0.9

1 answer

To calculate the total cost of the stamps, we first need to find the individual costs of the fifty cents and thirty cents stamps separately.

Cost of fifty cents stamp = $0.50
Cost of thirty cents stamp = $0.30

Now, we can find the total cost by multiplying the individual costs with the quantity purchased and then adding them together.

Total cost = (Cost of fifty cents stamp * Quantity of fifty cents stamps) + (Cost of thirty cents stamp * Quantity of thirty cents stamps)
Total cost = ($0.50 * x) + ($0.30 * 3)
Total cost = $0.50x + $0.90

Therefore, the total amount spent by Trisha on the stamps would be $0.50x + $0.90.
