11. At Price Chopper you are purchasing groceries and the bill comes out to be
Vinil7 [7]

9514 1404 393

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 function, B (x), models the estimated tuition cost where x is the number
zepelin [54]

The expression that completes the function b(x)​ is b(x) = 33741 * (1.028)^x

<h3>How to determine the expression of b(x)?</h3>

The given parameters are:

Initial value, a = 33741  

Rate, r = 2.8%

The cost of tuition each year since 2015 is represented as

B(x) = a * (1 + r)^x

This gives

B(x) = 33741 * (1 + 2.8%)^x

Evaluate

b(x) = 33741 * (1.028)^x

Hence, the expression that completes the function b(x)​ is b(x) = 33741 * (1.028)^x
