Answer: $30.44
Step-by-step explanation:
$30 20% of tht is 6
30-6=24
tax is 6.4% which is 1.94
24+1.94 which equals $25.94
tips is 15% 4.5 so we add that to $25.94
so total is $30.44
Answer:
8
Step-by-step explanation:
100 = x^2 + AC^2
17^2 = AC^2 + (21 - x)^2
289 = AC^2 + 21^2 + x^2 - 2*21*x
289 =<u> AC^2</u> + 441 +<u> x^2</u> - 42x
from 1st equation AC^2 + x^2 = 100
289 = 441 + 100 - 42x
289 = 541 - 42x
42x = 541 - 289 = 252
x = 252/42 = 6
so AC^2 = 100 - 6^2 = 100 - 36 = 64
AC = 8
Answer:
Yes.

The answer to this equation is 2
Answer: Chiara's monthly payment is $194.7
Step-by-step explanation:
The cost of the new natural gas barbecue for $2,100. She made a down payment 30% off the purchase price. This means that the amount of down payment made is
30/100 × 2100 = 0.3 × 2100 = $630
Amount left to pay would be
2100 - 630 = $1470
The formula for determining monthly loan payment is
A = P(r(1 + r)^n)/((1 + r)^n - 1)
There would be 9 monthly payments, so
n = 9
r = 0.055/12 = 0.0046
P = 1470
A = 1470(0.0046(1 + 0.0046)^9)/((1 + 0.0046)^9 - 1)
A = (1470 × 0.0049)/0.037
A = 7.203/0.037
A = 194.67
