Question

Aiko needs solid color and patterned fabric for a sewing project. Fabric costs $7.99 per yard. She needs 2 1/3 yards of solid fabric and some patterned fabric. Write two equivalent expressions for the total cost of the fabric​ Answers 1. quangkhai The two equivalent expressions for the total cost of the fabric are (7.99 × 7/3) and 18.64 ### Total cost • Cost of fabric per yard =$7.99
• Number of fabrics = 2 1/3 yard
Total cost = Cost of fabric per yard × Number of fabrics
= 7.99 × 2 1/3
= (7.99 × 7/3)
= 55.93 / 3
= 18.64
Therefore, the two equivalent expressions for the total cost of the fabric are (7.99 × 7/3) and 18.64

The two equivalent expressions for the total cost of the fabric based on the information are 7.99 (2¹/₃) + 7.99x and 18.64 + 7.99x.

### What is a mathematical expression?

A mathematical expression is a statement that involves two or more variables that require some mathematical operations.
Most commonly, a mathematical expression contains numbers, variables, and operators, which show a value after the mathematical operations.

### Data and Calculations:

Cost of fabric per yard = \$7.99
Required solid fabric = 2¹/₃ yards
Required patterned fabric = x yards
The total cost of the fabric = 7.99 (2¹/₃) + 7.99x
= 18.64 + 7.99x
Thus, the two equivalent expressions for the total cost of the fabric based on the information are 7.99 (2¹/₃) + 7.99x and 18.64 + 7.99x.
