Henry has $19, Dan has $57, and Melissa has $11
Step-by-step explanation:
Let x represent how much money Henry has
Since Dan has 3 times what Henry has, his amount is 3x
Since Melissa has $8 less than Henry, her amount is x - 8
Create an equation that sets these 3 values equal to 87, then solve for x
(x) + (3x) + (x - 8) = 87
5x - 8 = 87
5x = 95
x = 19
So, Henry has $19
Find how much Dan has by multiplying 19 by 3
19(3)
= 57
Find how much Melissa has by subtracting 8 from 19
19 - 8
= 11
So, Henry has $19, Dan has $57, and Melissa has $11
