John has $25,000 to invest in two bonds, one paying 5% and the other paying 9% interest. If John wants to make $2,000 total interest between the two accounts, how much should he invest in each account? Solve each problem using a system of equations.

Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.

Step-by-step explanation:

Total number of minutes per month lalo has on his cell phone plan = 1500

Number of minutes he has already talked in that month = 785

Number of minutes available to talk = total number of minutes he has - total number of minutes he has already used.

                                                           = 1500 - 785

                                                            = 715 minutes.

Thus, Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.
