If you're doing it mentally, you should find a common factor between the nominator and denominator that also multiplies to make 100.
So here,
Divide top and bottom by 6.
That gives you: 3/4
3/4 is 75%
3 x 25 = 75
So, to solve this problem you just have to add up all of the smaller parts.
First, we have our daily charge: $46.99
2 * 46.99 = $93.98
Next, we have our mileage costs, which will be
[ (miles driven) * (charge per mile) ] - (50 * 0.35)
(430 * 0.35) - 17.5
150.50 - 17.50 = $133
Finally, we add our daily rate to our mileage costs.
93.98 + 133 = $226.98

Answer:
aₙ = a₁ + (n-1) * 18 a₁ = -5
Step-by-step explanation:
aₙ = a₁ + (n-1) * d a₁ = -5 d = 13 - (-5) = 18
a₂ = -5 + (2 - 1) * 18 = -5 + 18 = 13
a₃ = -5 + (3 - 1) * 18 = -5 + 36 = 31
a₄ = -5 + (4 - 1) * 18 = -5 + 54 = 49
Answer:
400
Step-by-step explanation:
You divide 240 by 6 and then multiply by 10.
