Hey there! :D

Subtract 10 from 28. 

28-10= 18

Now, divide that by 3. (for her three friends) 

18/3= 6

Each friend got 6 erasers. 

I hope this helps!

Alex Ar [27]

Answer:

5 gigabyte

Step-by-step explanation:

Let the GB data at which the charge for both company is same be x

For Kodu

monthly fixed charge = $50

Per GB data charge over limit = $36

charge for X GB data = Per GB data charge over limit *x = $36*x = 36x

Total charge for Kodu for x gb data = monthly fixed charge +charge for X GB data = $50 +$36

For Fidu

monthly fixed charge = $35

Per GB data charge over limit = $39

charge for X GB data = Per GB data charge over limit *x = $39*x = 39x

Total charge for Fidu for x gb data = monthly fixed charge +charge for X GB data = $35 +$39

Given that at at X GB data charge for both the company is same then

50 +36x = 35 +39x

39x - 36x = 50-35

=> 3x = 15

=> x = 15/3 = 5

Thus, at 5 GB over the limit, charge for both the company will be same.
