Answer:
20.921
Step-by-step explanation:
I looked it up
89 x 20 = 1780 89 x 5 = 445 80 x 20 = 1600 9 x 20 = 180 80 x 5 = 400 9 x
D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
okay so first we need to multiply 160 on both sides
{18/32(160)=n/160*160 (160 cancels out)}
so once we finish our calculations on the left side we get n equals 90
{n=90}
There isn't anything there
