Answer:
The equation which gives the total cost y of x pounds of dried cherries is
Step-by-step explanation:
Given:
Cost of 3 pounds of dried cherries = $15.90
Cost of 5 pounds of dried cherries = $26.50
Cost of 9 pounds of dried cherries = $47.70
Let Number of of pounds of dried cherries be 'x'
Let Total Cost be denoted by 'y'
We need to find the equation for total cost y for x pounds of dried cherries.
First we will find the cost of each pound of dried cherries.
Now we know that;
3 pounds of dried cherries = $15.90
1 pound of dried cherries = Cost of 1 pounds of dried cherries
Hence By using Unitary method we get;
Cost of 1 pounds of dried cherries =
Total Cost of dried cherries is equal to Number of of pounds of dried cherries multiplied by Cost of 1 pounds of dried cherries.
framing in equation form we get;
Hence The equation which gives the total cost y of x pounds of dried cherries is
