Chapter 1.1, Problem 41E

To determine

A baker orders 162 eggs and each carton contains 18 eggs. And we have to select an equation from given alternatives which we can use to find the number of cartons $x$ and to solve the equation.

Answer to Problem 41E

(C) $18x=162$

And $x=9$

Explanation of Solution

Here the given number of cartons is $x$ and each carton contains 18 eggs. The baker orders a total of 162 eggs.

Then the number of cartons multiplied by the number of eggs that each carton contains should be equal to total number of eggs.

  $\Rightarrow x\times 18=162$

Hence the required equation is, $18x=162$

To solve this equation divide each side by 18,

  $\begin{array}{l}\frac{18x}{18}=\frac{162}{18}\\ \Rightarrow x=9\end{array}$

Therefore the number of cartons that baker would get on ordering will be 9.
