Brandon has $700 in a savings account at the beginning of the year. he withdraws $30 each week to go out to eat. he wants to find out how many weeks he can do this and have at least $150 in the account.

18 weeks

Step-by-step explanation:

Initial amount stored in savings account = $700

Final minimum amount required in the account = $150.

Thus,

The total amount of money he can spend = (700 - 150) = $550

Each week he is withdrawing $30 to go out to eat.

Since , maximum money he can spend should be multiple of 30 ,

Thus maximum he can spend $540

number of weeks he can do this =

                                                      = 18.

So, he can take out $30 each week to go out to eat for 18 weeks only.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer: b
