Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minu

Kay [80]

Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minute. Plan B involves a fixed charge of $15 per month and call charges at $0.08 per minute.

Plan A $10 + .10/minute

Plan B $15 + .08/minute

If 250 minutes are used:

Plan A: $10+$25=$35
Plan B: $15+$20=$35

If 400 minutes are used:

Plan A: $10+$40=$50
Plan B: $15+$32=$47

B is the correct answer. How to test it:

Plan A: $10+(.10*249 minutes)
$10+$24.9=$34.9

Plan B: $15+(.08*249 minutes)
$15+$19.92=$34.92

Plan A < Plan B if less than 250 minutes are used.

Which one is it A. B. C. or D.

nadya68 [22]

7x + 2y = 2
2x - y = 10

2y = - 7x + 2
- y = - 2x + 10

2y = -7x + 2
y = 2x - 10

$y=\frac{-7x+2}{2}$
y= 2x - 10

y = -3.5x + 1
y = 2x - 10

Now, let's find "x" first by doing a substituion !

2x - 10 = - 3.5x + 1
y = 2x - 10

2x + 3.5x = 1 + 10
y = 2x - 10

5.5x = 11
y= 2x - 10

$x = \frac{11}{5.5}=2$
y= 2*2 - 10 = 4 - 10 = -6

In short, the answer would be : y = -6 (Option B).

Hope this helps !
