Final answer:
To calculate the cost per yard of fabric, subtract the total cost of other items from the total amount spent and divide by the number of yards of fabric purchased.
Step-by-step explanation:
To find out how much each yard of fabric cost, we need to subtract the total cost of all the other items Melissa purchased from the total amount she spent and then divide it by the number of yards of fabric she bought.
- Calculating the total cost of ribbons: 6 yards x $1.25 per yard = $7.50
- Calculating the total cost of paint tubes: 3 tubes x $2.25 each = $6.75
- Calculating the total cost of thread spools: 4 spools x $1.25 each = $5.00
- Calculating the total cost of the other items: $7.50 + $6.75 + $5.00 = $19.25
- Calculating the total cost of everything except fabric: $32.25 - $19.25 = $13.00
- Calculating the cost per yard of fabric: $13.00 ÷ 4 yards = $3.25
Therefore, each yard of fabric costs $3.25.
