Nathan ordered one cheeseburger and one bag of chips for 3.75 jack ordered two cheeseburgers and three bags of chips for 8.25 kn
Elan Coil [88]

Answer:

cheeseburger is $3 and chips is $0.75

Step-by-step explanation:

Let price of cheeseburger be x while price of a bag of chips be y hence for the case of Nathan, we can write the equation as x+y=3.75. Similarly, for Jack, we can write it as 2x+3y=8.25

x+y=3.75 hence x=3.75-y and substituting this into the second equation we have

2x+3y=8.25

2(3.75-y)+3y=8.25

7.5-2y+3y=8.25

y=8.25-7.5=0.75

x=3.75-y=3.75-0.75=3

Therefore, price of cheeseburger is $3 and chips is $0.75

Sphinxa [80]

Answer:

Loss percentage = 40% (Approx)

Step-by-step explanation:

Given:

Cost price of home = $182,000

Sales price = $110,000

Find:

Loss percentage

Computation:

Loss = Cost price - Sales price

Loss = $182,000 - $110,000

Loss = $72,000

Loss percentage = [Loss / Cost price]100

Loss percentage = [72,000 / 182,000]100

Loss percentage = 39.5604

Loss percentage = 40% (Approx)
