Question

Parveen buys 3 small bags of peanuts she gives the shopkeeper £2 and gets 80p change what is the cost of one pag of peanuts?

Answer 1

$0.4

Explanation:

Let cost per bag = x

Number of bags purchased = 3

Amount given to shopkeeper = $2

Change gotten = $0.80

(Cost per bag * number of bags purchased) + change obtained = amount given to shopkeeper

(x * 3) + 0.80 = 2

3x + 0.80 = 2

3x = 2 - 0.80

3x = 1.20

x = 1.20 / 3

x = 0.4

$0.4
