Joe worked as a waiter at a charity banquet. He earned $17.50 for each hour worked. Joe also received a tip for this event in the amount of $35.80. In order to work the banquet, Joe had to rent a uniform which cost $21.38 for the day. Joe worked 4 hours at the event and 2.5 hours helping set up the night before. Joe used his money earned to repay a loan he owes his dad in the amount of $250. The expression below can be used to find Joe's new loan balance after paying his dad. 250 – 17.5(4 + 2.5) – (35.80 – 21.38) How much does Joe now owe his dad for the loan?

Joe still owes his dad $121.83

Step-by-step explanation:

Joe's new loan balance after paying his dad = amount he owes his dad - joes profit

Joe's profit from working as a waiter = Revenue - cost of renting a uniform

Revenue = amount earned for total hours worked + tips

total hours worked = 4 hours + 2.5hours = 6.5 hours

amount earned for total hours worked = 6.5 x $17.50 = $113.75

Revenue = $113.75 + $35.80. = $149.55

Joe's profit = $149.55 - $21.38 = $128.17

Loan balance = $250 - 128.17 = $121.83

Alternatively, the equation provided in the question can be used :

250 – 17.5(4 + 2.5) – (35.80 – 21.38)

250 - 113.75 - 14.42

= $121.83

- "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."
