Supposed five plain hamburgers cost the same as three super burgers. Also suppose that one super burger cost $.30 more than one

noname [10]

Answer:

1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25

Step-by-step explanation:

We have three conditions

(1) 5P = 3S

(2) S = C + 0.30

(3) P = C – 0.20 Substitute (3) into (1)

=====

(4) 5(C – 0.20) = 3S Substitute (2) into (4)

5(C – 0.20) = 3(C + 0.30) Remove parentheses

5C – 1.00 = 3C + 0.90 Add 1.00 to each side

5C = 3C + 1.90 Subtract 3C from each side

2C = 1.90 Divide each side by 2

C = $0.95 Substitute C into Equation (2)

=====

S = 0.95 + 0.30

S = $1.25 Substitute C into Equation (3)

=====

P = 0.95 – 0.20

P = $0.75

1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25

A fruit company delivers its fruit in two types of boxes: large and small. a delivery of 6 large boxes and 5 small boxes has a t

Afina-wow [57]

6 large + 5 small = 127 kg ------------ (1)
2 large + 3 small = 51kg ------------ (2)

(2) x 3 :
6 large + 9 small = 153 ---------------- (2a)

(2a) - (1) :
4 small = 26
1 small = 6.5kg ------------ (sub into equation 1)

6 large + 5 small = 127 kg
6 large + 5(6.5) = 127
6 large + 32.5 = 127
6 large = 127 - 32.5
6 large = 94.5
1 large = 15.75 kg

Answer: The small box weighs 6.5kg and the big box weighs 15.75 kg
