Karina earned $60 from her part time job. She spent 3/10 of it on food and 1/4 of it on music. How much money does she have left?
$27 is left.
Multiply 60 by 3/10 and by 1/4.
Subtract the product from 60.
55 1/2
3/10 * 60 = 180/10 = 18
1/4 * 60 = 15
15 + 18 = 33 she spent.
How much money does she have left?
To find out how much money Karina has left after spending some of it, we need to calculate the amounts she spent on food and music and subtract them from her initial earnings.
First, let's calculate the amount Karina spent on food. We know she spent 3/10 of her earnings on food, so we can multiply her earnings by 3/10:
(3/10) * $60 = $18
Karina spent $18 on food.
Next, let's calculate the amount Karina spent on music. We know she spent 1/4 of her earnings on music, so we can multiply her earnings by 1/4:
(1/4) * $60 = $15
Karina spent $15 on music.
Now, we can subtract the amounts Karina spent on food and music from her initial earnings to find out how much money she has left:
$60 - $18 - $15 = $27
Karina has $27 left.
