Mr. Jones rents an office in a building for $600 a month. His office has an area of 1,250 square feet. At the same rate, how much will it cost to rent an office with an area of 3,000 square feet?

$1440

Step-by-step explanation:

From the above question:

We know that the rate is

1250 ft² = $600

3000 ft² = x

Cross Multiply

1250ft² × x = 3000ft² × $600

x = 3000ft² × $600/1250ft²

x = $1440

Therefore, at the same rate, the cost of an office with an area of 3000 square feet is $1440

all it means is function 3
