Chapter 1.3, Problem 72STP

To determine

To find: The requirescups of wheat flour.

Answer to Problem 72STP

Therequires $10\frac{1}{4}$ cups of wheat flour.

Explanation of Solution

Given information:The given to made first type bread need $2\frac{1}{2}$ cups of flour and second need $1\frac{3}{4}$

Calculation:

Consider that the first type of bread requires $2\frac{1}{2}$ cups of flour and $2$ loaves of bread are made from this. This can be represented by $2\times 2\frac{1}{2}$

The total quantity can be determined by as follows.

  $\begin{array}{c}2\times 2\frac{1}{2}+3\times 1\frac{3}{4}=2\times \frac{5}{2}+3\times \frac{7}{4}\\ =5+\frac{21}{4}\\ =\frac{20+21}{4}\\ =\frac{41}{4}\\ =10\frac{1}{4}\end{array}$

Thus, it requires $10\frac{1}{4}$ cups of wheat flour.
