Step-by-step explanation:
Given : Adam is ordering pizza for a company party that he needs to have catered.
Company A charges $8 for each pizza and a delivery/set-up fee of $45. Company B charges $12 for each pizza and a delivery/set-up fee of $5.
To find : Which inequality can be used to find x, the least number of pizzas that can be ordered so that the total charge for Company A is less than the total charge for Company B?
Solution : Let x be the number of pizza
Company A charges $8 for each pizza and a delivery/set-up fee of $45.
Total charge of Company A is
Company B charges $12 for each pizza and a delivery/set-up fee of $5.
Total charge of Company B is
The total charge for Company A is less than the total charge for Company B
i.e, Inequality form
or x> 10
Therefore, Inequality is and value of x>10.
