Question

A local hotel rents a hall 300 and charges 65 per guest Y as in cost X number of guest Determine the total charge if 78 attended

Answer 1

Step 1:

Write the given data

Cost of renting hall = 300

Charge per guest = 65

Step 2:

Write an equation to represent the cost function

y = Total cost

x = number of guest

y = 300 + 65x

Step 3:

y = 300 + 65x

x = 75

Substitute x in the equation to find the total charge for 78 attendees.

$\begin{gathered} y\text{ = 300 + 65 }\times\text{ 78} \\ y\text{ = 300 + 5070} \\ y\text{ = 5370} \end{gathered}$

Final answer

The total charge of 78 attendees = 5370
