Atutoring service offers a free one-hour tutoring session. after a client signs up, the next 10 hours of tutoring are billed at a rate of $30 per hour. for all the hours after that, the client receives a discounted rate. if a client pays $664 for 25 hours of tutoring, what is the service's discounted hourly rate? a) $24.50 b) $25.54 c) $26.00 d) $26.56

C) $26.00

Step-by-step explanation:

No. of hours needed to be paid for = 25 - 1 = 24 (First hour is free)

Cost of next 10 hours = $30 x 10 = $300

No. of hours left to be paid for = 24 - 10 = 14

Cost of last 14 hours = $664 - $300 = $364

Discounted hourly rate = $364 / 14 = $26

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
