1)y=5-2/3
y=13/2
2) t=4 1/2+ 4 1/2
t=9
3) w= 3 5/8+2 7/12
w=29/8+31/12
w=15/2
ok so 68 customers everything morning times 7 days per week is 476 customer.
now we know that 476 x .67 = $318.92
she make 8.50 per week plus $318.92 from customers
now we have this equation of
500 = 8.5x + 318.92
find x you will know how many weeks she needs.
8.5x = 500 - 318.92
8.5x = 181.08
x = 181.08/ 8.5
x ~~ 21.3 weeks

- = -
8 32
12/32 divide by 4 on top and bottom = 3/8 (correct)
12/4 = 3
32/4 = 8
answer is 3/8

hope this helps
y = 20x
The graph passes through the origin , hence is of form
y = mx ( m is the slope )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (2, 40) and (x₂, y₂) = (4, 80) ← 2 points on the graph
m = 
= 
= 20
y = 20x
Answer:
Passes through (0,1) and (1,3).
3-1/1-0=2/1=2
The slope of this line is 2
