Henry and Emma decide to invest in bonds and stocks. Let x represent the number of bonds and y represent the number of stocks. For every bond Henry buys, he spends $100 , and for every stock, he spends $150 Henry spent a total of $650 Emma spends $150 for every bond and $100 for every stock. She spent a total of $850 Which system of equations represents the situation?
Answer
A
100 x plus 150 y is equal to 650 150 x plus 100 y is equal to 850
B
850 x plus 650 y is equal to 100 650 x plus 850 y is equal to 150
C
100 x plus 150 y is equal to 850 150 x plus 100 y is equal to 650
D
100 x plus 150 y is equal to 650 100 x plus 150 y is equal to 850
Explanation
Henry spends $100 per bond and $150 per stock, so his total is 100x + 150y = 650. Emma spends $150 per bond and $100 per stock, so her total is 150x + 100y = 850. These equations match choice D.
