Answer:
The cost of 30 gallons of gas is $74.7.
Step-by-step explanation:
- Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.
- The cost 24 gallons is $59.76 to him.
- Now we need to find the cost of 30 gallons.
- To solve this problem use a direct variation formula.
- Solve for constant variation.
Step 1 of 3
Here we need to find the cost of 30 gallons.
Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.
The cost of 24 gallons is $59.76 to him.
Let, x be the number of gallons and y be the cost or price for gas.
Use the formula for direct variation which is given by y=kx.
Step 2 of 3
Now substitute the value y=$59.76 and x=24.
Put value in y=kx, we get

Substitute value of k is y=kx, we get y=2.49x
Step 3 of 3
Now we need to find the value of y that is the cost for 30 gallons.
Again use direct variation formula y=kx and value of k and x, we get 

CD would be double AB, which is 148
Answer:
- Mode-The most repetitive number.
- Median:The number in the MIDDLE when they are IN ORDER.
- Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS.
- Range - THE BIGGEST minus the Smallest.
Step-by-step explanation:

The total bill was inclusive of the one-time payment of $50 and an additional payment of $25 per month. The only unknown variable here is the amount of months you've had the phone. This can be solved by isolating the unknown variable, like so:
Let: x = number of months
Total bill = one-time payment + monthly payment * number of months
$375 = $50 + $25x
375 - 50 = 25x
325 = 25x
325/25 = 25x/25
x = 13
Therefore, you've had the phone for 13 months.
