Answer:

$6.30

Step-by-step explanation:

The 100% of cost is $3.50. The greeting cards are mocked up 80%. This means the customers pay 100% and 80% so 180%. To find the new price, create a proportion of equal ratios:

[tex]\frac{x}{3.50} =\frac{180}{100}[/tex]

Solve for x through cross multiplying:

3.50(180) = 100(x)

630 = 100x

6.30=x
