tankabanditka [31]

Answer:

$9 or 9% less

Step-by-step explanation:

Original Price = OP

$75= OP

75 x .2 (20% discount) = 15

$15 discount

$75 - $15 = $60

$60 x .1 (service fee) = 6

$60 + $6= $66

Op ($75) - $66 = 9

$9 less than OP

How I check the percentage (probaly not how ur supposed to but ah well)

75 = 100%

75 + 25 = 100 but 25 more than 100%

66 + 25 = 91, also makes 75 100% again

100%-91%=9%

Find the sum of the first 20 terms of the arithmetic sequence 4, 10, 16, 22....
hammer [34]

n = 20

d = 6

a = 4

L = a + (n - 1)*d

L = 4 + (20 - 1)*6

L = 4 + 19*6

L = 118

Sum = (a + L)*n/2

Sum = (4 + 118) * 20/2

Sum = 122 * 10

Sum = 1220
