Lynn was shopping and found a purse that was marked with a discount of 1/3 off if the original cost of the purse was $80 how muc

sdas [7]

The amount paid by Lynn is $ 53.33

Solution:

Given that, Lynn was shopping and found a purse that was marked with a discount of $\frac{1}{3}$ off

Original cost of purse = $ 80

To find: Amount paid by Lynn

Discount = $\frac{1}{3} \text{ of original price }$

Therefore, discount price is given as:

$\text{ Discount } = \frac{1}{3} \times 80 = 26.67$

Thus discount price = $ 26.67

Amount paid by Lynn:

Amount paid = original price - discount price

Amount paid = 80 - 26.67 = 53.33

Thus amount paid by Lynn is $ 53.33
