Answer:
$189
Step-by-step explanation:
When dealing with a percentage you need to convert it into a decimal. You do this by moving the decimal two places to the left so 25. becomes .25
Next in the problem, it says Irma has a 25% of coupon. So you subtract 1-.25 to get .75
We do this because we are only paying for 75% of the total product.
Lastly, just multiply 252*.75 to get $189
Hope this helps!
