Julio is paid 1.4 times his normal hourly rate for each hour he works over 30 hours in a week. last week he worked 35 hours and earned $436.60. write and solve an equation to find julios normal hourly rate, r. explain how you know the answer is reasonable.

For 30 hours Julio is paid 30r dollars.

For the extra 5 hours he worked he earns 5*1.4r = 7r dollars

So the equation is

30r + 7r = 436.60

37r = 436.60

r = 436.60 / 37 = 11.80

His normal hourly rate is $11.80 answer

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
