Question 1128156

When the average daily balance of a customer checking account falls below $500 in any week the bank access a $5 service charge. What must Friday balance be to avoid the service charge.
Monday $540.
Tuesday $455.50
Wed $365.50
Thur $330.
<pre>Correct equation, with B being Friday's balance: {{{matrix(1,3, (540+455.5+365.5+330+B)/5, ">", 500)}}}
This should give you B, or a Friday balance that is {{{highlight_green(matrix(1,4, ">", "(GREATER", "THAN)", "$809"))}}}
