Question

Hudson went into a restaurant and bought 8 hamburgers, and a drink for himself. The total cost was $51.50
Pedro went into the same restaurant and bought 4 hamburgers and a drink for himself. The total cost
was $39.30
Let x represent the cost of a hamburger and y represent the cost of a drink

The equation that represents Hudson’s purchase is x + 8y = 51.50

The equation that represents Pedro’s purchase is 4x + y = 39.50


I need the answer for both, thanks

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
