Hey there! :)

Answer:

133 pieces.

Step-by-step explanation:

If 7 pieces of cardstock sell for $3, we can set up a proportion to determine the amount of pieces bought in pieces/ money spent:

$\frac{7}{3} = \frac{x}{57}$

Cross multiply:

7 · 57 = 3 · x

399 = 3x

Divide both sides by 3:

x = 133 pieces. This is the amount of pieces bought.

Nina [5.8K]

We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon

Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price

We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price

Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825

Hope this helps :)</span>
