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.
