Final answer:
In order to find out how much the first movie grossed, we can set up an algebraic equation, X + (X + $103 million) = $1513 million. Solving for X, we find that the first movie grossed $705 million.
Step-by-step explanation:
The student's question asks for the calculation of box office revenue for a movie when combined with its sequel and given the difference between their gross revenues. This is a typical algebra problem involving a system of equations. To solve it, let's define X as the gross revenue of the first movie, and therefore X + $103 million as the gross revenue of the sequel. The combined total of their gross revenues is $1513 million. We can set up the following equation:
X + (X + $103 million) = $1513 million
Solving this equation:
2X + $103 million = $1513 million
2X = $1513 million - $103 million
2X = $1410 million
X = $1410 million / 2
X = $705 million
Therefore, the first movie grossed $705 million.
