Hello!
To solve this, find the cost of a single light bulb first, by dividing 9 / 5.
9 / 5 ==> 1.80
One light bulb is $1.80
Now, multiply 1.80 by 7.
1.80 * 7 = 12.6
7 light bulbs cost $12.6
Hope this helps! ☺♥

Step-by-step explanation:
5 boxes will cose 5 x 15.40 = 77 normally.
according to the table, he will get 6.5% discount.
6.5 percent of 77 is 77x0.065 = 5.005 ≈ 5
There's a property of logs I want you to remember, that is:
log(a)ᵇ = b*log(a)
We'll be using this property to solve the question
<u>Finding x:</u>
log(2)ˣ = log(3)
x*log(2) = log(3) [using the property mentioned above]
x = log(3) / log(2) [dividing both sides by log(2)]
Hence, the correct answer is option E.
Answer:
Below
Step-by-step explanation:
Because it is $7 per day and x = the length of rental days, our equation will look something like this :

Answer:
4000
Step-by-step explanation:
100 - 14 = 86
Here we shall take 86 to obtain the number easily
X × 86/100 = 3440
X = 3440 × 100 / 86
So X = 40 × 100
X = 4000
