Question

1. val buys a computer for $920. if this is 115% of what the store paid for the same computer, how much did the store earn on the sale? lesson 3-3

Explanation:

Step1: Define store's cost as \( x \)

Let \( x = \) store's cost. Then \( 115\% \times x = 920 \), so \( 1.15x = 920 \).

Step2: Solve for \( x \)

\( x = \frac{920}{1.15} = 800 \).

Step3: Calculate store's earnings

Earnings = Selling price - Cost = \( 920 - 800 = 120 \).

Answer:

120
