Question

Hudson went into a restaurant and bought 8 hamburgers, and a drink for himself. The total cost was $51.50

Answer 1

Answer:

x=51.50-8y eqn (i)

$x = \frac{39.50 - y}{4} eqn(ii)$

from eqn (i) and (ii)

$51.50 - 8y = \frac{39.50 - y}{4}$

206-32y=39.50-y

166.5=7y

y=23.78

now putting the value of y in eqn (ii) we get

x=3.93
