Question

MRS. GREEN IS THE HEAD CHEF AT ABC BAKERY. THREE DOZEN OF HER WORLD-FAMOUS CINNAMON ROLLS CALLS FOR 4 OUNCES OF YEAST TO BE DISSOLVED INTO 2 CUPS OF WARM WATER. IF MRS. GREEN HAS BEEN CONTRACTED TO MAKE 1,000 ROLLS FOR A THANKSGIVING FEAST APPROXIMATELY HOW MANY POUNDS OF YEAST IS SHE GOING TO NEED?

1. 7 pounds 2. 38 pounds 3. 73 pounds 4. 111 pounds

Answer 1

7 pounds

Step-by-step explanation:

Mrs Green's initial production is three dozen cinnamon rolls. We need to convert this to number of rolls

That is 3*12= 36 cinnamon rolls

She uses 4 ounces of yeast

Converting the yeast to pounds

1 ounce= 0.0625 pounds

4 ounces= x

Cross-multiply

x= (0.0625 * 4) ÷ 1

x= 0.25 pounds

0.25 pounds was used for 36 cinnamon rolls

y pounds will be used for 1 cinnamon roll

Cross-multiply

y= (0.25 * 1) ÷ 36= 0.006944 pounds

Therefore the pounds of yeast that will be used for 1,000 cinnamon rolls is

Yeast amount = 0.006944 * 1,000

Yeast amount= 6.944 pounds~ 7 pounds
