I tried to work this out all I can think of is but than that just seems useless, cause there’s nothing you can do any further.
Hi again once again I need help setting up the equation for this, it is similar in spirit to my last question but still I can't figure out how to set up the equation , please help.
Bob has made $1980 annual interest from his two bank accounts. One of his bank accounts yields 6% interest and the other yields 9% interest , how much money would he have to have in each account?
Unless there's something subtle that we've missed, this question can't be solved.
Unless it means he made $1980 from each of his accounts, in which case the equations are:
0.06x = 1980
0.09y = 1980
A solution to either of these would be a valid solution for the question where $1980 is the total, you'd assume that either x or y would be zero. Or the amount could be anywhere in between.
[Paraphrase]Bob invested $25,000 into two bank accounts which gave him a combined annual interest of $1980. One account gave him a 6% annual return and the other gave him a 9%. How much would he have to have put in each of his accounts in order to get this amount of interest?
