Answer: B, $78
Step-by-step explanation:
If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.
20% x 65 = 13. So the tip for the dinner is 13 dollars.
Now we have to add it to the original dinner cost.
65 + 13 = 78.
Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!
24 + 3r = 100
Subtract 24 from both sides.
24 - 24 + 3r = 100 - 24
Divide
3r = 76
3r/3 = 76/3
r = 25.3
Rounded to 25.
They would have to be rewarded 25 times in order to have a party.
Answer: $104
Step-by-step explanation:
First you have to find 30% of 80. If 100% is 80, then 10% is 8. To get 30%, multiply 8 by 3 to get 24. So if 30% of 80 is 24, and you need to find the new price of the shoes because they were marked up 30%, then add 24 to the original priceof 80. $80+$24=$104
Well I think you should calculate 75 times 60 its 4200
