Answer:
$7.50
Step-by-step explanation:
2 yd= 1.25
we have 12 yd so 12/2= 6
6*1.25= 7.50
You have to get p by itself so add 18 to Both sides and -18 + 18 is 0 and 18+3 is 21 so p=21
So you subtract $22.89 from $54.73 to get a total of $31.84 and that’s how much the customer paid.
Slope=-5
as the line goes 5 down and 1 right
