<span>The phone company charges 10 cents to connect a call for one minute and 8 cents per minute after that. 
We call x minute to talk after the first minute.
We have 10+8x</span>≤100 (cents)
and 8x≤100-10
or 8x≤90 and x≤90:8
and x≤11.25
So: <span>How long could you talk on the phone for 1 dollar: it is 11 minute and 15 seconds</span>

What is the correct answer and why show your work
Anna11 [10]

Answer:

A7.45x = y

Step-by-step explanation:


We can use a ratio to solve this problem.  Take the total cost of the lunches and divide by the number of lunches.

y = total cost of lunches and

x = number of lunches

74.50             y

-------------- = ------------

10                     x


Using cross products

74.5 x = 10 y

Divide each side by 10

74.5/10 x= 10y/10

7.45x = y
