Answer 1

Answer:

Baseball gloves = 17 gloves  ||     Bats = 11 bats

Step-by-step explanation:

Let baseball gloves be x and bat be y

Possible Equations:

x + y = 28

29x + 14y = 647

-----------------------------------

make x the subject:

x + y = 28

x = 28 - y .........equation 1

29x + 14y = 647

x = (647 - 14y)/29 .........equation 2

----------------------------------------------------------------

Solve them simultaneously:

28 - y = (647 - 14y)/29

29(28 - y) = 647 - 14y

812 - 29y = 647 - 14y

-14y + 29y = 812 - 647

15y = 165

y = 11

So the number of bats he sold is 11 bats.

number of gloves he sold:  x = 28 - y

                                          :  x = 28 - 11

                                          :   x = 17

So number of baseball gloves he sold is 17 baseball gloves.
