Question

How mucho Does it cost to buy 12 meals if each 3
Meals cost $7.25$ explain please

Answer 1

So if you have 12 meals and each 3 cost $7.25 then the cost to buy them all is $29.

We can figure this out by dividing each of the meals into groups of 3, and we would get four total groups of 3.

Then we multiply 7.25 by 4 and we get 29, which is the final answer.

Answer 2

`\bf \begin{array}{ccll}meals&\$\\\cline{1-2}3&7.25\\12&x\end{array}\implies \cfrac{3}{12}=\cfrac{7.25}{x}\implies \cfrac{1}{4}=\cfrac{7.25}{x}\\\\\\ x=\cfrac{4\cdot 7.25}{1}\implies x=29`
