Answer:
Step-by-step explanation:
-We notice that this is a linear relationship which is generally expressed as:
Where
- x is the term
- y is the quantity at time x and
- c is the constant.
Given our constant value as 60 and the rate of change, m=7
let x be the row number and y the number of seats in the row.
-This is a linear relationship expressed as:
b. From a above, we have the linear relationship as y=7x+60
#To find the number of seats in the 18th row, we substitute x with the row number:
Hence, there are 186 seats in the 18th row.
