The price of a computer was decreased by 30% to £147. What was the price before the decrease?

Sunny_sXe [5.5K]

Answer:

£210

Step-by-step explanation:

A decrease of 30% represents 70% of the original cost.

100% represents the original cost

Divide the price by 70 to find 1% then multiply by 100 for original cost

original cost = $\frac{147}{70}$ × 100 = 2.1 × 100 = £210

y = 13.50x + 20
