Answer:
$3.51
Step-by-step explanation:
1 pound is $2.39 so divide by 2 and round up to the nearest whole number which is $1.12. Add $1.12(The cost of 0.5 pounds) to $2.39(The cost of 1 pound) to get $3.51 as your total.
It lands on floor 5.
10-9+19-3-12
1+19-3-12
20-3-12
17-12
5

Thats what you would use, so now 2/10 is .2 When you divide so you move the decimal so 20%
The percent increase is 20%
