Answer:

i)  Sally' s grocery bill = c - \frac{5}{100}c = 0.95c

   Therefore the correct option is B.)

ii)   Therefore the expression which represents the expected population  

    next year is given by :

    = p + \dfrac{7.5}{100} p   =   1.075p

Therefore the correct option is B.)

Step-by-step explanation:

Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 5%.

Let c represent the cost of Sally's groceries.

therefore the expression which represents Sally's grocery bill is given by :

Sally' s grocery bill = c - \frac{5}{100}c = 0.95c

Therefore the correct option is B.)

The population of a city is expected to increase by 7.5% next year If p represents the current population, which expression represents the expected population next year?

Let p = current population of a city.

Therefore the expression which represents the expected population next year is given by :

  = p + \dfrac{7.5}{100} p = 1.075p

Therefore the correct option is B.)

nignag [31]

Answer:

41

Step-by-step explanation:

Given Expression:

(4 x 9 - 21) \ 3+6^2

Multiply 4 and 9 to get 36.

36 - 21 / 3 + 6^2

Subtract 21 from 36 to get 15.

15/3 + 6^2

Divide 15 by 3 to get 5.

5+6^2

Calculate 6 to the power of 2 and get 36.

5+36
