Let the cost of one pound of candy be x and one pound of mint be y.
3x+2y=10.8 a
x+3y = 5.35 b
B*3 = 3x+9y = 16.05 b
b-a = 7y = 16.05-10.8= 5.25
y = 5.25/7 = 0.75
The cost per pound of mints is $0.75
The area of the following shape is 50
Answer with explanation:
The given statement is which we have to prove by the principal of Mathematical Induction

1.→For, n=1
L H S =2
R H S=1
2>1
L H S> R H S
So,the Statement is true for , n=1.
2.⇒Let the statement is true for, n=k.

---------------------------------------(1)
3⇒Now, we will prove that the mathematical statement is true for, n=k+1.

Hence it is true for, n=k+1.
So,we have proved the statement with the help of mathematical Induction, which is

D is the answer because it’s between -3.5 and -3.7
