Problema Solution
an Oceanside restaurant prices its fresh fish using a 90% markup over its cost. If it sells fresh red snapper for 19.57, what was the restaurant's cost for this fish?
Answer provided by our tutors
let 'c' represent the restaurant's cost, then:
19.57 = c + 0.9c
solving for 'c' we have:
c = 10.3
the restaurant's cost for the fish would then be $10.30
