The total cost in dollars for a certain company to produce x empty jars to be used by a jelly producer is given by the function c(x)=0.8x+40,000find c(50,000), the cost of producing 50,000jars.

80,000

Step-by-step explanation: Start by plugging in 50,000 into the function for x. This gives you C(50,000)=0.8(50,000)+40,000. Next, multiply 0.8×50,000=40,000. This makes the function C(50,000)=40,000+40,000. Finally, just add 40,000+40,000=80,000. Therefore, C(50,000)=80,000.

it would be 6xy and -16xy.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
