c = (5 + 2.25)r
c = 5r + 2.25
c = 5 + 2.25r
c = 5 + (5-2.25)r
প্রশ্নঃ The total cost of a bouquet of roses at a flower shop depends on the number of roses ordered. The vase costs $5, and each rose costs $2.25. Which equation can be used to find 'c', the total cost of a bouquet with 'r' roses?

Cost of the vase = 5
So, tatal cost, c = 5 + 2.25r
প্রশ্নঃ The area of a rectangle R with width 4 feet is equal to the area of a square S, which has a perimeter of 24 feet. The perimeter of the rectangle R, in feet, is :
perimeter of square=4a
so, area of square=6*6=36
according to the question,
area of rectangle=36
perimeter of rectangle=2*(9+4)=26 ft (ans)

প্রশ্নঃ If b <2 and 2x-3b=0, which of the following must be true?
given 2x-3b=0 or x =3b/2 and b<2
St 1: x>-3 lets consider possible value of b if b =-24 then x =-36 so x>-3 could be true but not must be true
St2: x<2 if b=1.9 the x= 3*1.9/2 or x> 2 so this condition could be true but not must be true
St3: x=3 for x =3 we need b=1 which is possible but again falls under could be true cause b can take any value Less than 2
St4: x<3 -------> or 3b/2<3 we get (3b-6)/2< 0 or 3b-6< 0 Or b< 2 which is same as the original given condition
প্রশ্নঃ Ms. Zareen purchased stock for Tk. 15,000 and 2/3 of it after its value doubled. She sold the remaining stock at 5 times its purchase price , what was her total profit?
2/3 of stock = 10000
1/3 of stock = 5000
2/3 doubled = 2*10000 = 20000
1/3 quintupled = 5*5000 = 25000
Total profit = Total selling price - Total purchase price of stock =
(20000 + 25000) - (10000 + 5000) = 45000 - 15000 = 30000 tk
