Answer:
i) Sally' s grocery bill = c - [tex]\frac{5}{100}[/tex]c = 0.95c
Therefore the correct option is B.)
ii) Therefore the expression which represents the expected population
next year is given by :
= p + [tex]\dfrac{7.5}{100}[/tex] 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 - [tex]\frac{5}{100}[/tex]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 + [tex]\dfrac{7.5}{100}[/tex] p = 1.075p
Therefore the correct option is B.)
