Question

Ken spent 1/5 of his allowance on a movie, 3/8 on snacks, and 2/7 on games. If his allowance was $20, how much did Ken have left? PLEASE HELP!

Answer 1

Answer:

He left with $2.786.

Step-by-step explanation:

Consider the provided information.

Ken spent 1/5 of his allowance on a movie, 3/8 on snacks, and 2/7 on games.

It is given that his allowance was $20.

The money spent on movie is:

$\frac{1}{5}\times 20=4$

He spent $4 for movie.

The money spent on snacks is:

$\frac{3}{8}\times 20=7.5$

He spent $7.5 for movie.

The money spent on games is:

$\frac{2}{7}\times 20=5.714$

He spent $5.714 for movie.

Subtract the money spent from total allowance as shown:

$20-4-7.5-5.714\\20-17.214\\2.786$

Hence, he left with $2.786.

Answer 2

1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07

Answer: $6.07 is the amount ken has remaining
