Rate of Daniel - x:
4.95 (40 ÷ 9 + x) = 40
22 + 4.95x = 40
4.95x = 18
x = 40 ÷ 11
Time for Paul to gather 40 bushels:
= 40/(40 ÷ 11)
= 40(11 ÷ 40)
= 11

Answer:
y = 7x +2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = 
= 
= 7
the line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = 7x + 2 ← equation of line
Solving a linear equation, we can conclude that each tin costs £0.75
<h3>How much does a tin of beans cost in pounds?</h3>
First, we know that Ed buys one box of eggs for £2.20.
Also two packs of bacon for £2.80 each.
And two tins of beans for X each.
Then the total cost is:
C = £2.20 + 2*£2.80 + 2*X
Now, we also know that when he pays with £10, he gets a change of £0.70.
Then we can solve the linear equation:
£10 - (£2.20 + 2*£2.80 + 2*X) = £0.70
£2.20 - 2*X = £0.70
£2.20 - £0.70 = 2*X
£1.50 = 2*X
£1.50/2 = X = £0.75
In this way, we can conclude that each tin costs £0.75
