Question

how many ice cream servings can the 5 sisters buy if they only want to spend 10.00$ on ice creams. Write an inequality. Ice creams is 2.80$

Answer 1

Let the number of ice-cream serving the sisters can buy be "s".

Each serving is $2.80, so the cost of "s" ice-creams will be:

`2.80s`

This cost cannot exceed 10 dollars.

10 dollars is the maximum.

So, we can say that "2.80s" is equal to or less than 10.

We write it in inequality notation:

`2.80s\leq10`

Solving for "s":

`\begin{gathered} 2.80s\leq10 \\ s\leq(10)/(2.80) \\ s\leq3.57 \end{gathered}`

So, the logical solution is that the 5 sisters can buy 3 ice-cream servings with their budget.
