B)
it is 15 more than A so the A has to go first
Answer:
26%
Step-by-step explanation:
Adding r% to a bill is equivalent to multiplying the amount by (1 +r%). Each resulting amount is rounded to the nearest penny.
__
<h3>tax</h3>
After the 6.5% tax was added, the bill was ...
$12.70 × (1 +0.065) = $13.5255 ≈ $13.53
<h3>tip</h3>
After the 18% tip was added to this amount, the total cost was ...
$13.53 × (1 +0.18) = $15.9654 ≈ $15.97
<h3>total</h3>
Then the multiplier of the original bill was ...
$15.97/$12.70 ≈ 1.25748... ≈ (1 +25.7%)
The total cost was about 26% more than the original bill.
If solving for x:
Because both equations are equal to Y, you can set both equations equal to each other:
5x+1=4x+8
Then it's a matter of simplification (subtract the 4x to the left side and subtract the 1 over to the right):
x=7
If solving for Y:
Plug x=7 into either equation and solve:
Y=4(7)+8
Y=36
