A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for a total revenue
stepladder [879]

Answer:

9 right-handed gloves and 3 left-handed gloves were sold.

Step-by-step explanation:

Given:  In one month, 12 gloves were sold for a total revenue of \$561.

            right-handed gloves cost \$45 and left-handed gloves cost \$52.

To find: How much of each type of gloves did they sell?

Solution: Let they sell x  right-handed gloves, and y left-handed gloves.

Now, cost of each right-handed gloves =\$45

cost of each left-handed gloves =\$52

Total revenue =\$561

So, we get

45x+52y=561\:\:\:...(i)

Also,  in a month 12 gloves were sold.

So, we get

x+y=12\:\:\:...(ii)

Now, from (ii) we get, x=12-y.

Putting x=12-y in equation (i), we get

45(12-y)+52y=561

\implies 540-45y+52y=561

\implies7y=561-540

\implies7y=21

\implies y=\frac{21}{7}

\implies y=3

Now, putting y=3 in equation (ii), we get

x+3=12

\implies x=12-3

\implies x=9

Hence, 9 right-handed gloves and 3 left-handed gloves were sold.
