Question

A chef uses 3 3/4 pounds of semolina flour and 1 5/8 pound whole wheat flour for each batch of pasta she makes.one week she uses a total of 86 pounds of flour. Write an equation to solve for b, the number of batches of pasta the chef makes during the week.

Answer 1

A) b= 86 / (3 3/4+1 5/8)

B) 16

Answer 2

16 batches is the answer.

Explanation:

Amount of semolina flour used for 1 batch of pasta =
`(15)/(4)` pounds

Amount of wheat flour used for 1 batch of pasta =
`(13)/(8)` pounds

Total amount of flour used =
`(15)/(4)+ (13)/(8)`

=
`(43)/(8)` pounds

Let the number of batches made during the week be = b

A total of 86 pounds of flour is used in a week to make 'b' batches

b=
`(86)/((43)/(8) )`

b = 16

Hence, a total of 16 batches are made in a week.
