Answer:
3y + x = 6
4y + 1.50x = 8.50
Step-by-step explanation:
Cost of walnut = $1.50
Cost of cashew = $1.00
Cost of dates = $1.50
Let
Dates = x
Cashew = y
Walnuts = 2y
Pounds of total mixture = 6 lb
Total cost of the mixture = $8.50
First equation (from Quantity)
Walnuts + cashew + dates = Total mixture
2y + y + x = 6
3y + x = 6
Second equation (from price× Quantity)
2y(1.50) + y(1.00) + x(1.50) = 8.50
3y + y + 1.50x = 8.50
4y + 1.50x = 8.50
Therefore, the system of equation to solve the question is
3y + x = 6
4y + 1.50x = 8.50
