In the system a +b = 7 and 1.29a + 0.496 = 6.63, a represents pounds of apples and b represents pounds of bananas. Anna (solution on the left side) and Marco (solution on the right sidej are finding and interpreting the solution. Is either of them correct? Explain. 1.29a + 0.49b = 6.63 1.29a + 0.49b = 6.63 1.29(7 - b) + 0.49b = 6.63 1.29a + 0.49(8 + 7) = 6.63 1.29 + 0.49a + 3.43 - 6.63 9.03 - 1.29b + 0.49b 6.63 0.49a - 3.2 -0.8b = -2.4 a- 1.9 b-3 a +b. 7, so b- 5. The solution (2, 5) means that 2 pounds of apples and 5 pounds of bananas were bought. The solution b= 3 means that 3 pounds of apples and 3 pounds of bananas were bought,
