Students deliver catalogues and leaflets to houses. One day, they have to deliver 384 catalogues and 1890 leaflets.
Each student can deliver either 16 catalogues or 90 leaflets in 1 hour.
Each student can only work for 8 hours.
All students hired are paid £51.30 per day, even if they don't work a full day.
If the minimum number of students are hired, how much will the wage bill be?

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
