Asha and Lucy are selling pencils in a school shop.

They sell boxes of pencils and single pencils.

Asha sells 7 boxes of pencils and 22 single pencils.

Lucy sells 5 boxes of pencils and 2 single pencils.

Asha sells twice as many pencils as Lucy.

Work out how many pencils there are in a box

Step-by-step explanation:

7x+22=2 (5x+2)

7x+22=10x+4 (-7x)

3x+4=22 (-4)

3X=18 (divide by 3)

X=6 pencils

check if the number is correct

asha = 7*6=42 42+22 is 64

Lucy = 5*6=30 30+2 is 3264/32 is 2

asha = 7*6=42 42+22 is 64Lucy = 5*6=30 30+2 is 3264/32 is 2there fore asha sells twice as many as Lucy
