Well, we need to divide $36.25 by 12.5. This will give us the per gallon price. So 36.25/12.5=2.90.
So regular gasoline is $2.90 a gallon
So, now we know this, if we add 14¢ to 2.90, we get $3.04. Now, we multiply 3.04 by 12.5=38. So, 12 and a half gallons of premium gas costs $38
Let x be the number of ordinary cars
Let y be the number of SUV's
The difference between the number of ordinary cars and the number of suvs is 17.
So x-y=17 ----> first equation
The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.
ordinary cars = SUV + 77.3% of SUV
x = y + 0.773y
x = 1.773y
Now we solve for y
We plug in x=1.773y in first equation
1.773y - y=17
0.773y = 17
y = 21.9922
Number of SUV's = 22
I think this is how it should look like
103 is the answer of your question
Solve
-1(x-6)(x+8)
-1(x^2+8x-6x-48)
-1(x^2+2x-48)
-x^2-2x+48
Hope this helps :-)
