Answer:

D.

Step-by-step explanation:

A function is represented by every input has only one output. Let’s look at each of the answer choices:

A. Input 4 notebooks, cost is $20 and input 5 notebooks, cost is $25. This is a function

B. Input 1 hour, charge is $20 and input 2 hours, charge is $40. This is a function

C. Input 1 hour, drove 50 miles and input 2 hours, drove 100 miles. This is a function.

D. Input 6 gum balls chewed, chewed in 2 and 3 hours. This is NOT a function. The input does not have only one output.

I hope this helps! :)

zaharov [31]

Answer:

96

Step-by-step explanation:

We will use the order of operations to solve the equation

7×8+1×40

multiplication before addition, so we do this first:

7×8=56

We change the equation to this:

56+1×40

Then we multiply:

1×40=40

We change the equation to this:

56+40

Then we add to solve:

56+40=96

Answer:

a) <u><em>The watch is cheaper in Geneva.</em></u>

b)  <u><em>The watch is cheaper by £20</em></u>

Step-by-step explanation:

a) In which city is the watch cheaper?

Step 1. Translate Pounds into Swiss Francs.

£145 * 1.55 = 224.75 CHF

Step 2. Determine which price is higher.

224.75 is greater than 193.75.

Step 3. Always answer a Word problem in complete sentences.

<u><em>The watch is cheaper in Geneva. </em></u>

b) By how much is it cheaper?

224.75 - 193.75 = 31

Translate CHF to Pounds.

31 / 1.55 = 20

<u><em>The watch is cheaper by £20.</em></u>
