Question

In June 2011, Justin Bieber had earned $17 million less than Lady Gaga earned over a 12-month period. The

total earned by the two artists over this time period was $123 million. Determine the amount of money Justin
Bieber earned in this 12-month period.

Answer 1

Justin Bieber earned $53 million in the 12-month period.

Step-by-step explanation:

The student's question is asking to determine the amount of money Justin Bieber earned in a 12-month period given that Justin Bieber had earned $17 million less than Lady Gaga and the total earnings of both was $123 million.

Let's denote Justin Bieber's earnings as J and Lady Gaga's earnings as G. According to the information provided, we have two equations:

1. J = G - 17 (since Justin Bieber earned $17 million less than Lady Gaga)

2. J + G = 123 (since the total earned by both artists is $123 million)

We can now solve these equations simultaneously. By substituting the first equation into the second, we get:

G - 17 + G = 123

2G - 17 = 123

2G = 123 + 17

2G = 140

G = 140 / 2

G = 70

Now that we have Lady Gaga's earnings, we can calculate Justin Bieber's earnings:

J = G - 17

J = 70 - 17

J = 53

Therefore, Justin Bieber earned $53 million in the 12-month period.
