Answer:  $5.16

==================================================

Work Shown:

72% = 72/100 = 0.72

72% of $3.00 = 0.72*3.00 = 2.16

The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars

-------

We can find this answer through this alternative route:

1.72*3 = 5.16

The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%

Answer:

marked up $2.16

total: $5.16

Step-by-step explanation:

3 dollars is 100 percent

30 cents is 10 percent

3 cents is 1 percent

So you will do 10 percent 7 times and 1 percent 2 times

30 cents times 7 is $2.10 + %0.06 so it is marked up $2.16

Total: $5.16

would be much appreciated
