Jen wants to buy a dress that originally had the price of $33, but now it is on sale 10% off. How much will Jen pay for the dr

valentinak56 [21]

Answer:

$29.70

Step-by-step explanation:

1. First, we have to find how much 10% of 33 is!

$\frac{10}{100} * 33$
$\frac{330}{100}$
$3.3$

2. Okay, now that we know 3.3 is 10% of 33, we need to subtract 3.3 from 33 to get the amount Jen will pay for the dress.

$33 - 3.3$
$29.7$

Therefore, Jen will pay $29.70 for the dress.
