Question

A car dealership sold 78 cars in April. The dealership wants to increase the number of cars sold by 30% in
May. How many cars will the dealership need to sell to reach their goal?

Answer 1

Answer:

111 cars

Step-by-step explanation:

30% of 78 is

78×30%=78×0.3=23.4

Cars needed to sell

78+23.4=111.4

Unless we can't have 0.4 of a car, we need to round that number, so 111.4≈111

Answer 2

The number of cars the dealership need to sell in May to reach their goal is 101.4 cars.

Given the following data:

• Number of cars sold in April = 78 cars

• Percentage increase = 30%

To find the number of cars the dealership need to sell to reach their goal:

Mathematically, percentage increase is given by the formula:

$Perecent\;increase = \frac{New\;value - Old\;value}{Old\;value} \times 100$

Substituting the given parameters into the formula, we have;

$30 = \frac{New\;value -78}{78}\times 100\\\\2340=100New\;value -7800\\\\100New\;value = 7800+2340\\\\100New\;value=10140\\\\New\;value=\frac{10140}{100}$

New value = 101.4 cars
