Answer:
4 x 8.50
100
= 0.34
8.50 - 0.34 = 8.16
Explanation:
a percentage is always over 100 so i 4 percent of 8.50 which gave me 0.34
Dont forget we are only focused on on the increase so we gotta subtract to make it normal from the original number which gives u 8.16...
Note dont forget it said an hour so multipy it by 1 hour since it said one hour which stills gives u the same answer
