Question

All star sports sells right handed and left-handed baseball gloves and one month 12 gloves were sold for a total revenue of $528 right handed gloves cost $48 each and left-handed gloves cost $36 each how many right handed gloves were sold

Answer 1

Write an equation for the total number of gloves sold

x + y = 12

y = (12-x); use this form for substitution

Write an equation for the total value of the gloves sold

48x + 36y = 528

replace y with (12-x)

48x + 36(12-x) = 528

48x + 432 - 36x = 528

48x - 36x = 528 - 432

12x = 96

x = 96/12

x = 8 rt handed gloves

then

12-8 = 4 left handed gloves

Check this in the 2nd equation

48(8) + 36(4) =

384 + 144 = 528 Ans- 8 rt hand gloves

Answer 2

rite an equation for the total number of gloves sold

x + y = 12

y = (12-x); use this form for substitution
