Suppose the linear cost function c(x) = 6x gives the cost for buying x items. if the items are sold in packages of 10, and no one can buy more than 5 packages, then the range of the function c is

D {0,60,120,180,240,300}

Step-by-step explanation: They come in packages of 10 and you can get 5.

6x10=60

6x20=120

6x30=180

6x40=240

6x50=300

40% off the regular price is the correct answer.

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
