Question

Roseanne bought 7 pairs of gloves and 4 pairs of mittens for $19.82 at an outlet store. later that day she returned and bought an additional 3 pairs of mittens for $8.92. how much did a pairs of mittens cost

Answer 1

Let g = the cost of a pair of gloves

Let m = the cost of a pair of mittens

 

7 pairs of gloves and 4 pairs of mittens costs $19.82.

7g + 4m = 19.82

 

3 pairs of mittens costs $8.92.

3m = 8.92

 

If you want to know the cost of mittens, solve the second equation for m. If you divide both sides of the equation by 3, m = 2.97333333. That means that a pair of mittens costs about $2.97

Answer 2

Each pair of mittens cost $2.84.  Three times $2.84 is $8.92.  The first part about the gloves and mittens is not needed to get the answer.
