To find: the cost of the shirt
Answer to Problem 1ST
The cost of the shirt is
Explanation of Solution
Given information: “A $48 sweater cost $6 more than twice as much as the shirt that goes with it”
Concept Involved:
Assign variable for the unknown that we need to find. Use the keywords in the statement to rewrite the statement to meaningful math equation.
“is” means =
“more than” means +
“twice” means 2 times
Solve the equation by getting the variable in one side of the equation and undoing whatever is done to it by performing reverse operation.
Calculation: Let ‘ x’ be the cost of the shift that we are trying to find. Rewrite the sentence by replacing the cost of shirt with x .
48 is 6 more than twice as much as x
Replace the keywords to get an equation representing the sentence given
Use the symmetric property of identity which states that if
In the process of getting x in one side of the equation subtract 6 on both sides of the equation
Combine like terms on both sides
Divide by 2 on both sides of the equation
Simplify fraction on both sides of the equation
Conclusion:
The cost of the shirt is
