You said that P = I · R · T
Divide each side by I · R : P / (I·R) = T
4,500 x 3.75% = 168.75
2,200 + 168.75 = He would earn $2,368.75 this month
Wish I had this job XD
Cut out 18%
100=all,
all-cut out=remaining
100-18=82
4hrs 20mins=240+20mins=260mins
82% of 260 is 0.82*20=213.2=3 hours and 33.2 minutes
he can runi s 3 hours and 33.2 minutes
All good and for number 6 you should draw an acute angle
