Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Answer to Problem 3STP

  $0.79

Explanation of Solution

Given:

A bakery sells cookies, doughnuts, and bagels. Cindy bought 3 cookies, 2 doughnuts, and 1 bagel for $4.84 . Andrew bought 10 cookies, 12 doughnuts, and 6 bagels for $25.12 . Linda bought 12 doughnuts and 10 bagels for $27.38 .

Calculation:

Let the cost of cookies, doughnuts, and bagels be x , y and z respectively.

On the basis of given information the following three system of equations can be set up as follows-

  3x+2y+z=4.84 .......... (1)

  10x+12y+6z=25.12 .......... (2)

  12y+10z=27.38 ......... (3)

Eliminating the x term from the equation (1) and (2)

  30x+20y+10z=48.4     .......(1)×1030x+36y+18z=75.36      .....(2)×3_{ subtracting}−16y−8z=−26.96     ......(4)

Solving the equation (3) and (4) to find the value of y

  48y+40z=109.52      .........(3)×4−80y−40z=−134.8     ......(4)×5_−32y=−25.28y=25.2832y=0.79

Therefore the cost of the doughnut is $0.79
