the temperature ,t, in Burrtown starts at 21 degrees F at midnight, when h=0. For the next few hours, the temperature drops 4 degrees every hour. which equation represents the temperature ,t, at hour h?
t =21-4h
Answer:
(100)^0=1
Step-by-step explanation:
This follows the laws of indices
let h be the number of hours then
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Thus Attorney A becomes a better deal at 5 hours
Answer:
A
Step-by-step explanation:
first option, as the decrease percentage is applicated on a greater number than the original
e.g.
A
a= 10
B
10 + 50% = 15
15 - 50% = 7,5
A will be greater then B by 25%
