Q. Jules is making a peanut butter sandwich with two slices of bread and chunky peanut butter. If the mass of two slices of bread is 6060 grams and the mass of the entire sandwich is 9292 grams, which of the following equations can be used to find x x , the amount of peanut butter Jules used in grams?
  1. Calculate Peanut Butter Mass: Let's denote the amount of peanut butter Jules used as xx in grams. We know the mass of the two slices of bread is 6060 grams and the total mass of the sandwich is 9292 grams. To find the mass of the peanut butter, we can subtract the mass of the bread from the total mass of the sandwich.\newlineCalculation: 9292 grams (total mass) - 6060 grams (mass of bread) = xx (mass of peanut butter)
  2. Write Equation: Now, we write the equation based on the calculation above.\newlineEquation: 9260=x92 - 60 = x
  3. Simplify and Find Value: We can simplify the equation to find the value of xx.\newlineCalculation: 9260=3292 - 60 = 32\newlineSo, x=32x = 32 grams
