Answer:
$911.25
Step-by-step explanation:
For 1 day the man works for 6 hours.
Then for 6 days the man will work for (6×6)hours = 36 hours
If the man makes $22.5 an hour, then for 36 hours, the man will earn ($22.5×36) = $810
Given, that the man gets a 12.5% raise, the we would have to apply the formula, where the 12.5% should be added to $810.
New Value/Old Value = 100 + rate/100
New Value/$810 = 112.5/100
By solving this equation, we get $911.25. So the man will earn $911.25 if he works for 6days a week.
Answer:
4x+y=34
Step-by-step explanation:
Linear equations can be written in 3 forms:
slope-intercept form
standard form
point-slope form
standard form's formula is ax+by=c,
now sub in 34 for c and 4 for a
4x+by=34
we can put in 1 for b since there is no other integers
4x+y=34
