Let x be the original price of the object.
After the 40% discount, the price of the object now becomes;
x-0.4x=0.6x
0.6x is our new price after the first discount.
Now if we want to find the price after the second discount, (5%)
That would come off to be;
0.6x-0.6(0.05)x=0.6x-0.03x=0.57x
Our last price is 0.57x
If you notice, there was a 43% discount in total, as it goes to 57% of its original price.
This is very non intuitive for some people, as they may think there will be a 45% discount.

Answer:
7y4
Step-by-step explanation:
7 is the highest number that can go into all three numbers
√a x √b =√axb so find 2 numbers that multiple to make the number (1 must be a square number)
√90 can be split into √9 x √10 and √9 is 3 so is 3√10 and the next questions are solved the same
√306 is 3√34
√73 is 3√8
√236 is 2√59
√3600 is 60
√5120 is 8√80
Answer:
y = 1/2x - 3/2
Step-by-step explanation:
y + 3 = 1/2 (x +3)
distribute and simplify
y = 1/2 x - 3/2
