Since PS = RS, the triangle PRS is isosceles. This means the angles SPR and SRP are congruent.

The interior angles of any triangle sum to 180° in measure. So we have

∠SPR + ∠SRP + 90° = 180°

2 ∠SPR + 90° = 180°

2 ∠SPR = 90°

∠SPR = a = 45°

David's dinner cost $24. He wants to leave a 20% tip. The tax rate is 8%. What is the total he will pay? (not $31.10)
Hitman42 [59]

Answer:

$30.72

Step-by-step explanation:

You were right with your answer, the teacher is probably just wanting you to tip on the subtotal (before tax) instead of the total total. Instead of doing total+tax+tip, we're going to figure out the tax and tip separately and then add it all together.

<u>Tipping on the subtotal (what your teacher wanted)</u>

20% of $24 = $4.80

8% of $24 = $1.92

$24+$4.80+$1.92=$30.72

<u>Tipping on the total (what you did)</u>

8% of $24 is $1.92

New total is $25.92

20% of $25.92 is $5.18

$25.92 + $5.18 = $31.10

Rufina [12.5K]

Answer:

Step-by-step explanation:

each box has 12 melon for 15 dollars:

the price of one melon : 15/12=1.25 dollar each

he bought 12 boxes of melon and paid 15 dollars for each :

12*15=180 dollars

total melon is : 12*12=144 dollars

he sold 3/4 of a melon : 3/4 *144=108

the cost of 108 : 108*1.25= 135 dollars

at a price of $ 1.6 = 108*1.6= 172.8

the rest of the melon sold at reduce price=

144-108= 36

over all profit = 15 %

180*(1+0.15)=207 dollars profit

selling 108 melons : $172.8

overall profit - profit from selling 108 melons: 207-172.8=$34.2

<h2>reduced price = 34.2/36=0.95 dollars</h2>
