Question

On Monday a shop receives $60.30 by selling bottles of water at 45 cents each

How many bottles are sold?

Answer 1

134 bottles

Explanation:

For this, I set up a proportion :

60.30/x = 0.45/1

60.30(1) = 0.45x

60.30/0.45 = 0.45x/0.45

x = 134 :)

Answer 2

134 bottles

Explanation:

conversion of dollars to cent:

$1 equals to 100 cents.

$60.30 will be (60.30*100) cents → 6030 cents

Bottles sold: total money / each bottle cost.
→ 6030 / 45
→ 134

So 134 bottles are sold for 45 cents to earn $60.30 or 6030 cents.
