Answer:
24 full weeks needed
Step-by-step explanation:
30 + 3x = 100
3x = 70
x = 23.333
24 weeks needed
So slope intercpet form
y=mx+b
m=slope
b=y intercpet
slope=5/3
in (x,y) form
x=3
y=5 is one point
subsitute and solve for b
y=mx+b
5=5/3 times 3+b
5=3/3 times 5+b
5=1 times 5+b
5=5+b
subtract 5 from both sides
0=b
equation is
y=5/3x+0 or
y=5/3x
9*(1/x)=33*(1/99)
9/x=1/3
x=27
the number is 27
