How to solve Algebra Word Problems?
Based on the information provided above, we can logically deduce that a linear equation that models the total amount of money earned by Hudson at this restaurant is represented by the following function:
y = 30 + 13t
Where:
t represent the number of tables he waits on that day.
y represent the total earnings.
When the number of tables he waits on that day is equal to 18, Hudson's total earnings can be calculated as follows;
y = 30 + 13t
y = 30 + 13(18)
y = $264.
When the number of tables he waits on that day is t tables, Hudson's total earnings can be calculated as follows;
y = 30 + 13t = $(30 + 13t).
