Answer:
Step-by-step explanation:
Part A:
Lets take the value of a=10
Thus a+1=b
10+1=11 , it means the value of b is 11
11>10 or b>a
Now take the value of a as -3
Therefore a+1=b
-3+1= -2
-2>-3 or b>a
The pair of values for a and b are: a=10 then the value of b would be 11;
And a=-3; then the value of b would be: -2.
Part B:
It is not possible to create a pair of values for a and be, in which the numerical relationship shown in the given conditional statement is false, therefore b>a if a+1=b....
The percentage decrease is 15%.
180 - 153 = 27 (price decrease)
10% of 180 = 18
5% of 180 = 9
18 (10%) + 9 (5%) = 27 (15%)
The price decreased by 27 and when you convert this into a percentage by dividing by the original price and then multiplying by 100, the result is a 15% decrease in the price.
To calculate the percentage decrease in the price, you first need to find out how much the price has fallen by. So subtract the new price (153) from the old price (180). This gives you 27.
Next, to convert this decrease to a percentage, you divide it by the original price (180) and then multiply by 100. So the calculation would be (27/180)*100 = 15%.
Therefore, the price of the item decreased by 15%.
