3y+x=12 in slope intercept form is y=-1/3+4
A=30+0.15t
B=30+0.15(200)=60
You can make an equation to solve this, but establishing knowns, unknowns, and relationships.
# in spring wash = x
# in summer = x + 14
Total Washes = 96
we know:
total = summer + spring
96 = (x) + (x + 14)
96 = 2x + 14
82 = 2x
"x" = 41
Using the slope-intercept form (y=mx+b) the slope is:
1.66666666
