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. 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

  2. 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.
