Answer:
$954.78
Step-by-step explanation:
Since it increases by 8.5%, all you have to do is multiply 879.98 by 1.085.
879.98 * 1.085 = $954.7783 = $954.78 (you always have to round to two decimal places with money)
All are correct because negative numbers are always smaller than 0 and bigger negative numbers always are less then smaller negative numbers such as -9 is smaller than -5
40+35.5 = 75.5
49.99 + 8.79 = 58.78
