Ann [662]3 years ago

Answer:

Please find attached the required inequality graph created with Microsoft Excel

Step-by-step explanation:

The  cost of each gumball = $0.50

The cost of each jawbreaker = $0.30

The amount Bob has to spend = $3.00

Let x represent the number of gumballs Bob buys and y represent the number jawbreakers Bob buys, we have;

0.50 × x + 0.30 × y ≤ 3.00

0.30 × y ≤ 3.00 - 0.50 × x

y ≤ 3.00/0.3 - 0.50/0.3 × x

y ≤ 10 - 5/3 × x

Therefore, we h

The monthly charge for a waste collection service is 1830 dollars for 100 kg of waste and 2460 dollars for 135 kg of waste. (a)
Ulleksa [173]

Answer:

C=18w+30

Step-by-step explanation:

We are given that The monthly charge for a waste collection service is 1830 dollars for 100 kg of waste

So, (x_1,y_1)=(100,1830)

We are also given that The monthly charge for a waste collection service is 2460 dollars for 135 kg of waste.

So, (x_2,y_2)=(135,2460)

We are supposed to find a linear model for the cost, C, of waste collection as a function of the number of kilograms, w.

So, we will use two point slope form :

Formula : y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

Substitute the values

y-1830=\frac{2460-1830}{135-100}(x-100)

y-1830=18(x-100)

y-1830=18x-1800

y=18x-1800+1830

y=18x+30

y denotes the cost

x denotes the weight

So, Replace y with C and x with w

C=18w+30

So, a linear model for the cost, C, of waste collection as a function of the number of kilograms, w is C=18w+30
