Answer:
s ≥ 21.25
Step-by-step explanation:
Beth's weekly payment consists of two parts:
fixed amount = $225
variable amount = $20 per sale
We can write the equation representing her weekly payment as follows:
P = 225 + 20s where P is the total weekly payment and s is the number of sales
Now, we are given that she wants to make at least $650 this week. This means that her payment this week should be equal to or more than $650
We can write the inequality as follows:
225 + 20s ≥ 650
Now, we can easily solve for s as follows:
20s ≥ 650 - 225
20s ≥ 425
s ≥ 21.25
This means that to make at least $650 in the week, the amount of her sales should be at least $21.25
Hope this helps :)
