Question

3 glasses and 3 mugs costs £18. 6 glasses and 4 mugs costs £32. Find the cost of a glass. Find the cost of a mug.

Answer 1

Answer:

one glass = £ 4.46

one mug = £ 1.305

Step-by-step explanation:

let the cost of one glass be x and one mug be y

according to 1st condition

3x + 4y = 18.6 eq 1

according to 2nd condition

6x + 4y = 32.0 eq 2

subtract eq1 from 2

on solving we get

x =4.46

y = 1.305

cost of on glass is £ 4.46 and one mug is £ 1.305

Answer 2

Answer: Glass =£4 Mug=£2

Step-by-step explanation:

Mug= m

Glass=g

3g+3m=18

6g+4m=32

(3g+3m=18) X2 =6g+6m=36

(6g+6m=36)-(6g+4m=32)=

2m=4

m=2

6g+12=36

36-12=24

6g=24

24/6=4

m=2

g=4
