A conference centre charges £120 to hire a room, with an additional charge of £8 for each delegate.
(a)
Find the total cost (including room hire) of a conference with 30 delegates.
(b)
Write down a formula for the total cost, C,in £,ofhiring a room for a conference with N delegates.
a.) the total cost (including room hire) of a conference with 30 delegates is= $360
b.)the formula to solve this problem is
C=120+8(30)
hope that helps:)
Minor adjustment required:
b.)the formula to solve this problem is
C=120+8N
(a) To find the total cost, we need to calculate the cost of room hire and add it to the cost of delegates.
The cost of room hire is £120.
The cost per delegate is £8.
Therefore, the total cost (including room hire) of a conference with 30 delegates can be calculated as follows:
Total cost = Cost of room hire + Cost per delegate × Number of delegates
Total cost = £120 + £8 × 30
Total cost = £120 + £240
Total cost = £360
So, the total cost of hiring a room for a conference with 30 delegates is £360.
(b) To write down a formula for the total cost, C, of hiring a room for a conference with N delegates, we can use the information given.
The cost of room hire is fixed at £120.
The cost per delegate is £8.
Using this information, we can write the formula as:
C = £120 + £8N
So, the formula for the total cost, C, in £, of hiring a room for a conference with N delegates is C = £120 + £8N.
