Answer:
John and Pam are paid $8.5 for each hour worked. John's share of the money is $29.75.
Step-by-step explanation:
Let x = the hourly salary. John worked for 3.5 hrs, and Pam for two. We can represent this using the equation:
3.5x + 2x = 46.75, where the coefficients equals the amount of hours.
Let's solve for x!
5.5x=46.75
x = 46.75/5.5 = 17/2 = 8.5
John and Pam are paid 8.5 dollars per each hour worked.
To figure out John's share of the money, we will multiply the wage by the hours he worked.
8.5 x 3.5 = 29.75
Profit = Revenue - Costs
P(x) = (-0.32x² + 270x) - (70x + 52)
P(x) = -0.32x² +270x -70x -52 . . . . . . . . eliminate parentheses
P(x) = -0.32x² +200x -52
Answer:
5(9+6)
5×9=45
5×6=30
