matias stepmother uses 30% off coupon to buy the ingredients for huevos rancheros she spends $28

what is the regular price r of the ingredients before the discount?​

Respuesta :

The original total of the ingredients was 40 dollars

Answer:

$40

Step-by-step explanation:

To determine the regular price r of the ingredients before the discount, we have to consider that $28 represents 70% of the regular price as this amount has a 30% discount and with that, find the price that represents 100%:

$28 → 70%

 r    ← 100%

r=($28*100%)/70%= $40

The regular price r of the ingredients before the discount is $40.
