Answer: x = $25.89
Step-by-step explanation:
This is a two step problem. First we need to determine the number of gallons the car uses to drive the 250 miles:
250/28 ≈ 8.93 gallons
Then we just multiply the number of gallons by the price:
8.93 x 2.90 = $25.90
Alternate solution: Use a proportion. Since 1 gallon costs $2.90 and produces 28 miles, we can set up the following proportion:
2.90/28 = x/250
Cross-multiply and solve:
28x = 725
x = $25.89 (There is a one cent difference due to a rounding error in the first solution. This solution avoids that error.)
For better understanding think of it this way. There are hundred customers, 60 orders coffee 35 orders pie and 30 does not order pie or coffee.
This means that 70 does order coffee or pie or both. Out of those 70 people 10 will not order coffee and 35 will not order pie. Thus 70-10-35=25 will order both coffee and pie.
P=0.25
Step-by-step explanation:
The first term of the AP (a) = 3
and common difference (d) = 8-3= 5
therefore, a+(n-1)d = 78
=> 3+(n-1)5= 78
=> n-1=75/5
=> n-1 = 15
=> n= 16
16th term of the AP is 78
