Answer:
The percent increase is 75%
Step-by-step explanation:
2.94 ÷ 1.68 = 1.75
1.75 x 100% = 175%
175% - 100% = 75%
PEMDAS- order of ops.
1st problem you need to divide 6/2 and then add8 and the second you divide 6/2 then add 8.
To complete the 100% of (the job) washing, Roland needed 4 Hours & Sam, 3 hour,
Mind you 100% = 1
Find for each one the (job) achieved in 1 hour:
Roland achieved 1/4 & Sam 1/3 each one in 1 hour.
In one hours both will achieve 1/4+1/3 =7/12
So they will complete 7/12 (of the job) in 1 hour & for a time = t they will complete 100% (or 1) of the job, that is 1/t =7/12 & t=12/7 =1.71 hour
