Question

Mdm Soh bought 288 eggs at \[ $2.95 \] for 12 eggs. How much did she pay for all the eggs?

Answer 1

Hint: Here in the given question, Mdm Soh bought 12 eggs at \[ $2.95 \] and we are asked to find for 288 eggs how did she pay, hence to find the amount, we need to find how many dozens are there for 288 eggs, as mentioned 12 eggs for \[ $2.95 \], hence with respect to the data given we need to calculate the pay.

Complete step-by-step answer:
Let us write the given data:
Mdm Soh bought 12 eggs at \[ $2.95 \] i.e.,
 \[ \to \] 12 eggs = \[ $2.95 \]
We need to find for 288 eggs how much she paid i.e.,
 \[ \to \] 288 eggs =?
We are actually told that 1 dozen eggs i.e., 12 eggs costs \[ $2.95 \], so let's find out how many dozens are there for 288 eggs.
 \[ \Rightarrow \dfrac{{288}}{{12}} = 24\]
Hence, we got that 24 dozen of eggs at \[ $2.95 \] each, and for 288 eggs we need to consider the number of dozens, so we have:
 \[24 \times 2.95 = 70.80 \]
Therefore, she paid \[ $70.80 \] for 288 eggs i.e., for all the eggs.
So, the correct answer is “ \[ $70.80 \]”.

Note: The key point to solve is that, we need to consider the given data and compare it with the asked data. As the ratio should exist between the quantities of the same kind. While comparing two things, the units should be similar. There should be significant order of terms and the comparison of two ratios can be performed, if the ratios are equivalent like the fractions.
