Question

A mother gives $20 to her daughter to buy some school supplies if the kid spends $219. How much did she spend of her own money.

Answer 1

To answer this all you have to do is subtract the amount of money given to her from the amount of money spent so in this case, 219-20=199

So she spent $199 of her own money

Answer 2

Subtract the total spent with the amount the mom gives

219 - 20 = 199

The daughter spends $199 of her own money

hope this helps
