Question

The cost of two pizzas and one burger is Rs 400. Form a linear equation in two variables for the given situation and draw the graph. Also, from the graph, find the cost of 1 burger if the cost of 1 pizza is Rs 150.
pls ans as fast as possible

Answer 1

Answer:

2x+y=400

y=400-2x

when x = 100, y= 400-2*100

y=400-200

y=200

when x = 50, y= 400-2*50

y = 400-100=300

when x = 150, y = 400-2*150

y = 400-300 = 100

when x = 200, y = 400-2*200

y = 400-400 = 0

draw a graph for this

is cost of one pizza is 150 then cost of 1 burger is

2x+y=400

2*150+y=400

300+y=400

y=400-300=100
