Answer:

  $181.19

Step-by-step explanation:

The coupon means you will pay 70% of the bill. The tax means you will pay 105.65% of the amount after the coupon is applied. Your final bill is ...

  $245 × 0.70 × 1.0565 ≈ $181.19

_____

Your bill after the coupon is applied will be ...

  bill - 0.30×bill = bill(1 - 0.30) = bill×0.70

The amount after tax is added is ...

  charge + 0.0565×charge = charge(1 +0.0565) = charge×1.0565

Since the final bill is the product of these factors, the order of application does not matter. Conventionally, tax is applied last, so that accounting with the tax collection authority is properly maintained.

The answer will be the biggest number, by which you can divide both 28 and 32. So you can divide them in 4 groups (28/4=7 girls per group & 32/4=8boys per group)

Answer

x=33

Step-by-step explanation:

since they're both on the same line we must equal them to 180.

18 + x + 4x -3 = 180 (Now you simplify terms)

5x + 15 = 180 (Subtract the 15 from both sides)

5x = 165 (divide by 5 to isolate the variable)

x = 33 (Hope I was able to help :) )

Log7^x-log7^3=1 <br>if anyone can help me with this problem please help me
vagabundo [1.1K]
Log7 (x+3) - log7 (x-3) = 1
log7 [(x+3) / (x-3)] = 1
raise both sides to power of 7
(x+3) / (x-3) = 7
7x – 21 = x + 3
6x = 24
x = 4
