Question

describes the number of sales she needs to make to reach her goal?

at least 47 sales
at most 47 sales
at most 17 sales
at least 17 sales

Answer 1

at least 17 sales

Explanation:

On Wednesday she wants to earn 128.

Per day value = 60

128-60=68

She still needs to earn 68.

68 divided by 4=The number of sales needed to get 68 dollars=17

Thus she needs to make at least 17 sales, at most means maximum but she wants to earn AT LEAST 128 which means she wants more thus, answer is 4th option.
