Question

A sporting goods store sells right-handed and
left-handed baseball gloves. In one month, 15
gloves were sold for a total revenue of $702.
Right-handed gloves cost $42 and left-handed
gloves cost $51.
How many left-handed gloves did they sell?

Answer 1

Let l= left hand and r=right hand gloves

Answer 2

set up these two equations
l+r=15
42r+51l= 702

Answer 3

okay

Answer 4

and subtracting l on both sides on the first equation gives you r=15-l

now substitute this into the second equation

Answer 5

so itll be 42(15-l) +51l=702

Answer 6

correct. and now you want to solve for l.
you can start with distributing the 42

Answer 7

the question doesnt ask for right hand

but if you want, to fidn the right, you just substitute 8 for l in one of the original equations to solve for r.

and yes, 7 is corect
