Answer: 10 hours
Explanation:
1) Fernando's earnings:
10 + 4h ← 10 is a fix charge, h is the number of hours and 4 is the rate per hour
2) Fernando's savings
0.30 (10 + 4h) ← 30% = 30 / 100 = 0.3
3 + 1.2h ← distributive property
3) Brenna's earnings
6h ← h is the number of hours, 6 is the rate per hour
4) Brenna's savings
0.25(6h) ← 25% = 25/100 = 0.25
1.5h ←0.25 × 6 = 1.5
5) Equal savings
3 + 1.2h = 1.5h
1.5th- 1.2h = 3 ← transpose terms
0.3h = 3 ← combine like terms
h = 3 / 0.3 = 10 ← divide by 0.3
Answer: h = 10

Answer:
The second function represents an even function.
Step-by-step explanation:
A function g(x) is said to be even if g(x) = g(-x). All that is needed is to replace x with -x in each equation, simply it and assess whether the equation remains unchanged. If the equation is identical to the original one then it is said to be even.

$0.30
Step-by-step explanation:
1 bar of candy = $0.20
3 bars of candy = $0.50
To solve, multiply for both:
If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:
9 x 0.20 = $1.80
If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:
9/3 = 3
3 x 0.50 = $1.50
Subtract the total cost of the individual from the pack:
$1.80 - $1.50 = $0.30
. $0.30 is your answer.
