To find the discount of an item you put the rate which is 25% over 100 and move the decimal point to the right this would leave you with 0.25.You then times $40 by 0.25 which leaves you with $10 so $10 is your discount.
To find the sales price of the dress you subtract the discounted price from the original price so it would be $40-$10 which is $30 so your sales price is $30.

Answer:
After 4 weeks they have $413
After 5 weeks they have $485 (more than enough money)
Step-by-step explanation:
we know that here are 3 people saving up this money and we know that they have already saved 125 dollars.
if each saves $24 per week... 24*3=72 (total profit per week)
for 4 weeks... 72*4=288
288+125(already saved up)= 413
If they go one more week and save up another 72 dollars in 1 week this will bring them past their goal
