OpenStudy (misty1212):
lets call \(x\) the amount of $5 deposits ok?

OpenStudy (misty1212):
then since the total is 14, the amount of $3.50 deposits is \(14-x\)
11 years ago
OpenStudy (misty1212):
we have
\[5x+3.50(14-x)\] as the total amount of money so we can solve
\[5x+3.50(14-x)=59.50\]

OpenStudy (gottennis121):
are you doing the total? not each one separate into 59.50?
11 years ago
OpenStudy (misty1212):
may be easier if we multiply both sides by ten and solve \[50x+35(14-x)=595\]
11 years ago
OpenStudy (misty1212):
multiply out and combine like terms on the left to get \[50x+490-35x=595\] or
\[15x+490=595\]

OpenStudy (misty1212):
subtract 490 from both sides, then divide by 15 to get your answer !!
