Price per lemon= 20.50÷2= 10.25
Price for 7 lemons= 7 * 10.25 =71.75
The first choice. -3 is the party to the left of the vertical all line. 2 is the part to the right. that segment is 5 units long
Just divide then subtract
95/83= 1.14= move decimal to right one time so it would be 11.4 then subtract 11.4 from 95= 95-11.4= about $83.55
I = {2.666666667, 1.166666667
11, 3, -3, -12
Hope this helps :)
