Answer:
Company one charges $11 + $0.16 per min.
Then if you talk for x minutes, the cost will be:
C₁(x) = $11 + ($0.16 per min)*x
For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:
C₂(x) = $20 + ($0.11 per min)*x
Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.
C₁(x) = C₂(x)
$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x
($0.16 per min)*x - ($0.11 per min)*x = $20 - $11
($0.05 per min)*x = $9
x = $9/($0.05 per min) = 180 mins
If you speak for 180 minutes, the cost is the same in both companies.
Answer:
x = 5/8 = 0.625

Answer:
£159.82
Step-by-step explanation:
Decrease of 39% of £262
39/100 × £262
0.39×262
102.18
So the decrease will be
262-102.18
159.82
So the final answer is £159.82
Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
