Rhonda uses 0.25 pounds of butter to make a batch of her grandmother’s cookies. She needs to make 4.5 times the recipe for the school bake sale, and an additional two batches for her family. How much butter does Rhonda use to make all the cookies?

1.625 pounds of butter is my best answer for this equation.

Step-by-step explanation:

I multiplied .25 by 4.5 and then added .50

1.625 pounds of butter, or 1 12/20

Step-by-step explanation:

First, we must recognize that 4.5 times the recipe is just asking you to multiply the butter for 1 batch by the size of the batch for the bake sale. (.25 x 4.5) =1.125

Do not forget that she must make two more batches, or .5 pounds of butter.

(.25+.25=.5)

By adding the bake sale amount by the extra batches for her family we can decifer that she needs 1.625 poinds of butter. (1.125+.5=1.625pounds)

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
