Ответ:
mandiy sells 66 pounds of fudge and 85 pounds of toffees
Step-by-step explanation:
Let x represent the number of pounds of fudge that Mandy sells in one month.
Let y represent the number of pounds of toffees that Mandy sells in one month.
They make an average of 151 pounds of fudge and toffee combined each month. This means that
x + y = 151
They sell a pound of fudge for $9.74 and a pound of toffee for $6.76. It means that x pounds of fudge will cost $9.74x and y pounds of toffees will cost $6.76y
Mandy's averages $1,217.44 each month in fudge and toffee sales. It means that
9.74x + 6.76y = 1217.44 - - - - - - - 1
Substituting x = 151 - y into equation 1, it becomes
9.74(151 - y) + 6.76y = 1217.44
1470.74 - 9.74y + 6.76y = 1217.44
- 9.74y + 6.76y = 1217.44 - 1470.74
- 2.98y = - 253.3
y = - 253.3/-2.98
y = 85
x = 151 - y = 151 - 85
x = 66
