So, you need to calculate: 3(340)=1,020 He uses 1,020 grams. So, the sum of the money received for bracelets, rings, and necklaces, will equal 245: 5x 20x 15x 45=245 So, you have one equation that you can solve for x, which is the number of bracelets sold: 5x 20x 15x 45=245 40x 45=245 40x=200 x=5 Remember that x equals the number of bracelets sold.
But, you cannot simply subtract this from the total mass of the bag of flour, because the bag of flour is stated in kilograms. 2.27(1000)= 2270 grams Now, subtract the amount of grams of flour Oliver used from the total grams in the bag of flour: 2,270-1,020=1,250 5.
