    Answer:

    She pays $240 for 8 lessons.

    Step-by-step explanation:

    We need to set up equivalent ratios so we can cross-multiply and solve for x, the amount Angela pays for 8 lessons. Make sure to have both the costs in the numerator, and the number of lessons in the denominator. If you mix it up, this won’t work.

    \frac{120}{4} = \frac{x}{8}

    Cross-multiply:

    120*8 = 4x

    Solve for x:

    960 = 4x

    960/4 = x

    x = $240
