0.05/2= 0.025
Step 2:
1-0.025= 0.975

Earning rate = $15.25 per hour + 3% of total sales
Total hours worked = (25 days)*(8 hours/day) = 200 hours
Total sales = $2,050.00
3% of total sales = 0.03*($2050) = $61.50
Total earnings = (15.25 $/hour)*(200 hours) + 61.50
= $3111.50
Answer: $3,111.50
All functions are relations, but not all relations are functions. A function is a relation that for each input, there is only one output.
EXPLANATION;
Functions are relations that have only one output for any unique input. To tell whether a graphed relation defines a function, you can use the vertical line test.
2+7+7+2+2+4 divide by 6 = mean
7 times 2 divided by 2=median
X=0.2
All you have to do is simplify both sides of the equation. Add 3x to both sides. Then subtract 0.8 from both sides.
