Answer:
D.$45.58
Step-by-step explanation:
The monthly charge for 300 kWh of electricity during the second period will be:
$6.08 + $0.13(250) + $0.14(50)
$6.08 + $32.5 + $7
= $45.58
The first 250 kWh of electricity used will be at the range of 0 - 250 and the remaining 50 kWh will be at the range of 251 - 360.
Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33

Answer:
x =82
Step-by-step explanation:
2/5 (x − 17) = 26
Multiply each side by 5/2
5/2 *2/5 (x − 17) = 26*5/2
x-17 =65
Add 17 to each side
x-17+17 = 65+17
x =82
