The advisable maximum amount of debt payment is 20 % of the monthly pay per month. so <span>Dave's take home pay per month is $2,200. so the maximum dollar debt he should have would be:
debt = 0.2 ( 2200)
debt = $ 440 is the maximum debt he should have</span>
We can get 10% of 300 by doing 300 / 10 which is 30. 70 / 10 is 7, so we need 7 lots of 10% to work out 70%. Therefore, 30 * 7 students said that their favourite colour was blue, which is 210.
