It’s Friday night and you do not feel like cooking dinner so you decide to order 2 large pizzas. The pre-tax total is $25.98; the delivery person delivers your pizza in a timely manner. How much of a tip should you give the delivery person for the service? Hint: 10% of the bill (excluding tax), at least $1 for bills up to $10. You should tip 15%-20% for a difficult delivery.

$25.98 excluding tax is remarkable but including tax it should be around $26 and in my opinion delivering on a Friday and in a timely manner no less they should be tipped 20% so it would be around $31 a pretty reasonable tip if you ask me.

Steps I took:

1.( 25.98 + 10% = 26.08).

2. ((round up)).

3. (26 + 20% = 31.2).

4. ((round up again)).

5. (and you get $31).

Have a nice day!    Nice to see you again! :3

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
