Step-by-step explanation:
Answer: $594
Step-by-step explanation: the formula is PxRxT/100
P stands for Principal= $3600. R stands for Rate= 2.75%. T stands for Time= 6 years. We substitute the value in the formular. We have 3600x2.75x6/100=594
To find the discount, multiply 60 by .2, which is 12. Now subtract 12 from 60. The trousers should cost $48 now because the cost has been reduced by 20% of 60, which is $12.
Answer:
5
Step-by-step explanation:
x^2-7x=30
x^2-7x-30=0
a = 1, b = -7, c = -30
sqrt(b^2-4ac)
sqrt(49+120)
sqrt(169)
13
-b +/- 13
7 + 13 = 20
7 - 13 = -6
2a = 2
20/2 = 10
-6/2 = -3
we know x>0, so it cant be -3. so now its just 10 - 5
