State your variables and what they represent. write a linear function describing the situation. use the function to solve the problem. a phone costs $8 per month, plus 10 cents per message unit. how much is the monthly bill if 40 message units are used?

y = 0.10x + 8, $12

Step-by-step explanation:

y = monthly bill

x = number of message units

Each message unit costs $0.10, so the cost of x message units is 0.10x.  The phone adds $8 to the monthly bill.  Therefore:

y = 0.10x + 8

If x = 40, then:

y = 0.10 (40) + 8

y = 4 + 8

y = 12

The monthly bill is $12.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
