<span>We can quickly calculate a ten percent tip by moving the decimal place one to the left. So a 10% tip on $85.00 would be $8.50. We can then take half of that tip to calculate the remaining 5%. $8.50 / 2 = $4.25. The sum of these two results is equal to a 15% tip. $8.50 + $4.25 = $12.75. The correct answer is D.</span>
It depends on if a letter can be repeated.If yes, then the answer is:
26x26x26x26x26x26=308,995,776
If the letters cannot be repeated, then:
26x25x24x23x22x21=165,765,600
Total discount for 10 group tickets = 10 · 0.05t
Amount of discount per ticket = 0.05t
Number of tickets = 10
Cost of buying 10 single tickets = 10t
Solution:
Cost for single ticket = t dollars
Discount percent per ticket = 5%
Number of tickets bought = 10
Total discount for 10 group tickets = Number of tickets × Discount amount
= 10 × 0.05t
Total discount for 10 group tickets = 10 · 0.05t
Amount of discount per ticket = 5%t
=
t
= 0.05t
Amount of discount per ticket = 0.05t
Number of tickets = 10
Cost of buying 10 single tickets = 10t
150 is the perimeter of the pool
From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

Hence, the distance is 250×30=7500 ft
