Question

Haman needs to bake at least 250 cupcakes for a bake sale. He can bake 45 cupcakes in one hour. Which inequality shows minimum numbers of hours that haman must bake to mark at least 250 cupcakes?

Answer 1

Given that Haman needs to bake at least 250 cupcakes for a bake sale,

`\begin{gathered} h\ge250 \\ \text{where h is the number of cupcakes he bakes} \end{gathered}`

and he bakes 45 cupcakes in one hour.

Let the number of hours he needs to use to bake at least 250 cupcakes be represented by x.

Thus, the total number of cupcakes he bakes is evaluated as

`\begin{gathered} \frac{45\text{cupcakes}}{1\text{ hour}}* x\text{ hours } \\ =45x \end{gathered}`

Thus, we have

`45x\ge250`

The first option is the correct answer.
