So before she earned 100%
then she took a 8% cut
100-8=92
if 59000=100% of x then
x=92%
59000/100=x/92
multiply both sides by 92 to clear fraction under the x term
5428000/100=x
54280=x
her salary after was $54280
By letting x=0 and then solving for y
The jupiter does a full rotation for 1407 h and 30 min
a.
Let x = # of hours
Let y = cost to rent skates
3 + 2x = y
b.
(Plug in 8 for x, because it is the # of hours)
3 + 2x = y
3 + 2(8) = y
(PEMDAS or order of operations)
3 + 16 = y
19 = y
It costs $19 to rent skates for 8 hours.
