Question 1160249
<br>
A discount of 15% multiplies the price by 0.85.
A discount of 15% followed by a discount of 10% on the already discounted price multiplies the price by (0.85)(0.90).<br>
The price of the first shirt will be (400)(0.85) = 340.
The price of the second shirt will be (400)(0.85)(0.90) = 340(0.90) = 306.<br>
The total cost of the two shirts will be PhP(340+306) = PhP 646.<br>
