Question

A baker bought 7500 grams of flour for$19.20.How much did each kilogram of flour cost?

Answer 1

Cost of 7500 grams of flour bought = $ 19.20
Cost of 1 gram of flour = $ 19.20/7500
1 kilogram = 1000 grams
So, cost of 1 k.g of such flour = $(1000x 19.20/7500)
                                              = $192/75
Then, turn it into decimal and you will get your answer to the question.

Answer 2

7500g=7.5kg Cost per kg=19.20/7.5=$2.56
