After a day of shopping, Hannah spent $150. This is 75% of the amount she got from her mom. How much money did she get from her
azamat

Answer:

Hannah got $200 for her mom

Step-by-step explanation:

With the numbers in this question you don't even have to worry about percentages.

You can think of it in quarters:

75% is 3 quarters of 100%

(25% + 25% + 25% + 25%)

$150 is 3 quarters of $200

($50 + $50 + $50 + $50)

Hope this helps and isn't a confusing way of explaining it! :)
