A car owner estimates that the fixed costs per year to own his car are \(\$ 7400\). His car averages 25 miles per gallon of gas. He wants to limit his annual car expenses to \(\$ 11,000\). If gas costs \(\$ 4\) per gallon, find the number of miles he can drive per year.

For exercises 65-86, (a) solve. (b) check. $$ \frac{2}{3}(n-1)+\frac{1}{6}=n-\frac{1}{2} $$

The cost for standard shipping of an order of textbooks from an on-line retailer includes a fixed cost of \(\$ 3\) per shipment plus \(\$ 0.99\) per book. Find the cost of shipping 12 textbooks.

A house cleaning company charges \(\$ 25\) per visit plus \(\$ 18\) per hour of cleaning. Find the number of hours the company will clean if the customer wants to limit the total charge to \(\$ 70\).

A taxi company charges a flat fee of \(\$ 2.40\) for the first mile plus \(\$ 2.60\) for each additional mile. Find how many additional miles a customer can travel for \(\$ 18\).

For exercises 89-92, solve. Use a calculator to do the arithmetic. $$ -24,598+p=89,457 $$

For problems \(89-92\), do the arithmetic with a calculator. The area \(A\) of a rectangular playground is \(28,800 \mathrm{ft}^{2}\). The length \(L\) is \(180 \mathrm{ft}\). Solve the formula \(A=L W\) for \(L\), and use it to find the width \(W\) of the playground.

For problems \(89-92\), do the arithmetic with a calculator. The volume \(V\) of a beaker of turpentine is \(325 \mathrm{~mL}\), and the mass \(M\) of the turpentine is \(283.16 \mathrm{~g}\). Use the formula \(D=\frac{M}{V}\) to find the density of the turpentine. Round to the nearest thousandth.

Solve: \(7(2 c-1)=15(c-3)-c\)

For problems 97-100, the symbol > means "greater than," and the symbol \(<\) means "less than." Replace the blank with < or \(>\) to create a true statement. -3_____-8
