Explanation of Solution
Given:
Weight of rice (in pounds) | Weight of beans (in pounds) | Total cost (in $) | |
Kate | 3 | 1 | 4.50 |
Elisa | 4 | 2 | 7.00 |
The statements given are:
Calculation:
Let x be the cost of rice and y be the cost of beans.
Given that Kate has purchased 3 pounds rice and 1 pound beans for $4.50
Multiply equation (1) with 2,
Subtract equation (2) from equation (3), so that y is eliminated
Substitute the value of x in equation (2).
Therefore, the cost of one pound of rice is $1.00 and the cost of one pound of beans is $1.50
Conclusion:
Therefore, the correct statements are A, D, E and F.
