Final answer:
After deducting the cost of the meal from her budget, Sarah has 450 dhs left. Since each dress costs 150 dhs, the equation is 150 dhs × x = 450 dhs, which means Sarah can buy 3 dresses.
Step-by-step explanation:
To determine how many dresses Sarah can buy within her budget, we must first account for the additional expense of her meal. We start by subtracting the cost of the meal from Sarah's total budget of 500 dhs.
The cost of the meal is 50 dhs, so the remaining budget for dresses is:
500 dhs - 50 dhs = 450 dhs
Now, we can define the number of dresses Sarah can buy as x. Each dress costs 150 dhs, so the equation to represent the situation is:
150 dhs × x = 450 dhs
To solve for x, we divide both sides of the equation by the price of one dress, which is 150 dhs:
x = 450 dhs / 150 dhs
This results in:
x = 3
Therefore, Sarah can buy 3 dresses with her remaining budget, after purchasing the meal.
