Charges for a bag of sweets are 3p per sweet and 15p for a bag. If I spent £3.75 on a bag of sweets, how many sweets did I buy?

Explain your strategy to a partner. Did they use the same strategy? Which is easier?

120 sweets

Step-by-step explanation:

Cost per sweet = 3p (3 cents)

Cost per bag = 15p (15 cents)

If amount spent on a bag of sweet = $3.75, number of sweets purchased ;

$3.75 = 3.75 * 100 = 375 cents

Hence,

Number of bags = 1

Let number of sweets = x

3x + 15 = 375

3x = 375 - 15

3x = 360

x = 360/3

x = 120

Number of sweets = 120
