Question

Roberto’s monthly pay is $4349.70. Each month he uses 2/5 of his pay for his household expenses and 1/10 for his car payment. He deposits the rest into his savings account.

How much does Roberto deposit into his savings account each month

Answer 1

2/5=4/10
4/10+1/10=5/10
10/10-5/10=5/10

4347.70/10=434.77
434.77x5=2173.85 he put into his saving account

hope this helps
