A bike store sells scooters at a 54% markup. If the store sells each
scooter for $69.30 then what is their
non-markup price?

$45.00

Step-by-step explanation:

154% → $69.30

100% → $69.30 x 100/154 = $45.00

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

$12. that is my answer.
