Question

You work for 6.5 hours at a rate of $11.50 / hour. You buy dinner that costs $12, and give a $20 tip. How much money are you left with?

Answer 1

Answer:

Step-by-step explanation: working time: 6.5 hours

Money: 11.50 or 11.5 per hour

Dinner Cost: 12

Over head expenses/Tips: 20

Left money: 11.5×6.5-(12+20)

= $74.75-32=42.75 Answer

Answer 2

Answer:

$42.75

Step-by-step explanation:

Given that,

Earning rate per hour (60 min) = $11.50

Total work done (hr) = 6.5 hr = 390 min

Let x be the total earnings in 6.5 hr (390 min),

Total earnings in 6.5 hr (390 min) (x) = Total work done * Earning in 60 min /  60 min

= 390 * 11.50 / 60

=$74.75

Now,

Money Spent = $12 +$20 =$32

Money left = 74.75-32 = 42.75

Therefore the total money left = $42.75.
