We want to find the place value of 9 in 8.00231497.
The number 9 is placed 7 places beyond the decimal point. This implies that its value is 7 orders of 10 less than 8 and its place value is ten-millionths.
40h is what you start out with since it costs 40 ever hour. then you add the service charge which makes it 40h + 125, and then since the total charge is 1205, that would complete the equation.
