Explanation:

Givens

4 scones

1 loaf of bread

Total cost = 3.30

Equation

Let the loaf of bread = b

Let the scones = s

Cost = b + 4s

Solution

Substitute the givens into the equation

b + 4s = Cost

90 + 4s = 3.30 Subtract 90 from both sides

90-90 + 4s = 3.30-90 Combine

4s = 2.40 Divide by 4

4s/4 = 2.40/4

s = 0.6 of a pound

Answer: 1 scone = 60 pence.
