Eddi Din [679]

Answer:

C(g) = 10 + 15g

C'(g) = 80

The monthly charges of Company C for using 2 Gigabyte of data usage.

Step-by-step explanation:

The cell phone plan from Company C costs $10 per month, plus $15 per gigabyte for data used. The plan from Company D costs $80 per month, with unlimited data.

Now, the monthly cost in Company C for using g gigabyte of data will be

C(g) = 10 + 15g ........ (1)

Again, the monthly cost in Company D for using g gigabyte of data will be

C'(g) = 80 ......... (2)

Now, from equation (1), the statement C(2) = 10 + 15 × 2 = 40, means that monthly charges of Company C for using 2 Gigabyte of data usage. (Answer)

BY using eight eights and addition only can you make 1000?????/

creativ13 [48]

If u add 125 times 8 it will equal 1000
becouse
$8*125=1000$
then
$\frac{1000}{8} =125$
you also can combine it (if this is what are you looking for..)
$888+88+8+8+8=1000$
or any other combination like:
$88+888+8+8+8=1000$
or:
$8+8+888+8+88=1000$
