First, let's define variables:
A = adults
C = children
Okay, now that's done, time to set up the two equations required to solve:
10a + 7c = 6549
a + c = 783
One way you can solve this is to set up the second equation to isolate a variable. For example,
a = -c + 783
Using this, we can plug it into the first equation and solve for c.
10(-c+783) + 7c = 6549
-3c = -1281
c = 427
Now, use the value of 427and plug it in either equation to solve for a.
a + 427 = 783
a = 356
356 adult tickets were sold, and 427 children tickets were sold.
Cost per gallon of gasoline = $3.95 per gallon.
Total number of gallons of gasoline Mr.Endo buys = 13.6 gallons.
We need to find the total cost of 13.6 gallons of gasoline.
<em>In order to find the total cost of 13.6 gallons of gasoline, we need to multiply it by cost of each gallon of gasoline.</em>
Therefore, cost of 13.6 gallons of gasoline = 13.6 × 3.95
On multiplying 13.6 by 3.95, we get 53.72.
<h3>Therefore, Mr.Endo spend a total $ 53.72 on gasoline.</h3>
Answer:
The calculation for annual premium is explained below:
Step-by-step explanation:
Here we are given as:
DRF = 1.75
time period = 6 month = 2 times a year
basic rate = 750
Her annual premium will be:
= 2625
Hence Wanda's annual premium will be 2625.
So, start with the growth formula
A=P(1+r)^t then plug in the values
6200=5200(1+.038)^t
then divide both sides by 5200
1.1923076923=1.038^t
then take the log of both sides
log(1.1923076923)= t log(1.038)
then divide both sides by the log(1.038)
4.7161004299=t
then round it to the nearest whole number
5=t
so about 5 months
