Answer:
Explanation:
To solve this problem, we can set up a proportion to find the number of diapers Jacklyn's baby brother will go through in 28 days.
Let's start by writing the proportion:
(18 diapers / 4 days) = (x diapers / 28 days)
To solve for x, we can cross-multiply:
18 * 28 = 4 * x
Next, we simplify the equation:
504 = 4x
To isolate x, we divide both sides of the equation by 4:
504 / 4 = x
x = 126
Therefore, Jacklyn's baby brother will go through 126 diapers in 28 days.
