The total cost of the bags of candy that Harun and Breelyn bought is 3H + 3B dollars. The amount of money they had leftover is $30 minus the total cost, which can be expressed as:
30 - (3H + 3B)
30 - (3H + 3B)
The total amount they had is $30. The cost of each bag of candy is $3.
The expression to represent the amount of money they had leftover can be written as:
$30 - ($3 * (H + B))
In this expression, (H + B) represents the total number of bags they bought. Multiplying this by the cost per bag ($3) gives us the total amount spent on the bags. Subtracting this from the total amount they had gives us the amount of money they have leftover.
To represent the number of bags Harun bought, we can use the variable "H," and to represent the number of bags Breelyn bought, we can use the variable "B."
The amount they spent on candy bags can be calculated by multiplying the number of bags by the cost per bag. So, the amount spent by Harun is given by "H x $3" and the amount spent by Breelyn is given by "B x $3."
To find the amount of money they had leftover, we subtract the amount spent on candy bags from the total amount they had. The expression to represent the amount of money they had leftover can be written as:
$30 - (H x $3 + B x $3)
or
$30 - 3H - 3B.
