Question

18. Curry powder is sold at $7.45 per 100 g. How much money will Thuy need in order to buy 3 kg of curry powder?

Answer 1

$7.45 = 100g
x = 3kg ( 3 × 1000) = 3000g
$7.45 = 100 g
X
= 3000 g
(100 × x) = (7.45 × 3000)
100x = 22350
100x/100 = 22350/100
X=$223.5

Answer 2

Explanation:

$7.45 = 100g

x = 3kg( 3 × 1000) = 3000g

∵ $7.45 = 100g

x = 3000g

(100 × x) = (7.45 × 3000)

100x = 22350

100x/100 = 22350/100

x = $223.5
