Harun and Breelyn have $30 to spend on a bag of candy at the CANDY SPOT. Each bag costs $3. Given that H and B represent the number of bags that Harun (H) and Breelyn (B) bought, which expression can be used to represent the amount of money they had leftover?
A 3H + 3B - 30
B 30 - 3H - 3B
C 30- 3H +3B
D 30 +3H-3S
B 30 - 3H - 3B
The correct expression to represent the amount of money they had left over is:
B) 30 - 3H - 3B
To represent the amount of money Harun and Breelyn had leftover, we need to subtract the total cost of the bags they bought from the initial amount of money they had.
The total cost of the bags they bought can be calculated as the product of the number of bags Harun bought (H) and the cost per bag ($3), plus the product of the number of bags Breelyn bought (B) and the cost per bag ($3). So, the total cost is 3H + 3B.
To find the amount of money they had leftover, we subtract the total cost from the initial amount of money they had, which is $30. Therefore, the expression that represents the amount of money Harun and Breelyn had leftover is 30 - (3H + 3B).
So, the correct answer is B) 30 - 3H - 3B.
