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 30+3h-3s
B 10-3h-3b
C 3h+3b-30
D 30-3h+3b
B 10-3h-3b
To determine the expression that represents the amount of money they had leftover, we need to calculate the total money spent on candy and subtract it from the initial amount they had.
The total amount spent on candy is found by multiplying the number of bags bought by the cost per bag. Since Harun bought H bags and Breelyn bought B bags, we can calculate the total money spent as:
Total money spent = Number of bags bought * Cost per bag
= H * $3 + B * $3
= 3H + 3B
To find the amount of money they had leftover, we subtract the total money spent from the initial amount they had:
Amount of money leftover = Initial amount - Total money spent
= $30 - (3H + 3B)
= 30 - 3H - 3B
Therefore, the correct expression that represents the amount of money they had leftover is option B: 10 - 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 total amount they had, which is $30.
Since Harun bought H bags and Breelyn bough B bags, the expression that represents the amount of money they had leftover is:
D) 30 - 3H + 3B
