Let the cost of the shirt be y and the price by the which the shirt is sold is 2y. This means that at 15% discount, the shirt is sold at 1.7 of its original cost.
Answer: 69/15=4 and remainder 9
Step-by-step explanation: Since 15 x 4 = 60, 15 can't go into 9 so 9 in the leftover
It would be C.88-x and there are 36 black keys on an 88 key piano
I would multiply 60 by 3, since its 300+%
60 x 3 = 180
From there I would then add at least half of 60, which is 30
180 + 30 = 210
Since it is 380, I would just add another 20 to the equation to get around :
210 + 20 = 230
This should be a good enough estimate that is close to 380% of 60 <span />
