A grocery store is running a special on frozen dinners. If a customer buys a family-size dinner for \( \$ 8 \), he or she can buy any number of single-serve dinners for just \( \$ 2 \) apiece. Write an equation that shows how the total cost, \( y \), depends on the number of single-serve dinners purchased, \( x \). Do not include dollar signs in the equation.

\( \operatorname { CD } ( + 5 t - 2 ) + ( - 3,6 \)

Solve. \[ \sqrt{x-7}+\sqrt{x+8}=5 \] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The solution(s) is/are (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) B. There is no solution.

Oof 1 The manager of a small company that produces roof tile has determined that the total cost in dollars, \( C(x) \), of producing \( x \) units of tile is given by \( C(x)=200 x+600 \) while the revenue in dollars, \( R(x) \), from the sale of \( x \) units of tile is given by \( R(x)=230 x \). Find the break-even point and the cost and revenue at the break-even point.
