First you have make the 2 and a half into 5/2. Then you have to find a common denominator of the two fractions, which would be 8. So the 7/8 you dont need to do anything to but the 5/2 you do... so multiply both the top and the bottom by 4 so you can get 8 on the bottom. that would be 20/8. now you can add them. so 7/8 + 20/8 = 27/8
Answer:
100 +3s≥ 160
You must sell as least 20 items
Step-by-step explanation:
You make 100 plus 3 dollars per sale
100 +3s
It must be at least 160
100 +3s≥ 160
Now we need to solve to see how many sales
100 +3s≥ 160
Subtract 100 from each side
100-100 +3s≥ 160-100
3s≥ 60
Divide each side by 3
3s/3≥60/3
s≥20
You must sell as least 20 items
