18.50/100 = 0.1850
0.1850 x 20 = 3.70
18.50 - 3.70 = 14.80
14.80/100 = 0.1480
0.1480 x 6 = 0.888
14.80 + 0.88 = 15.68
the final cost would be $15.68
The letters are called variables. Sometimes, they are called literals.
In the formula d=rt, d means distance, r means rate, and t means time.

The sequence is going up by 4 so u have to multiply each term by four and the -5 is it’s 0th term as well it’s beginning so you have to input that in the equation as well
4(50) - 5 = 200 - 5 = 195
I’m not very good at explaining so I hope u get it
