Let x be taco salads, and y be drinks.
The equations are as follows:
1) 2x+2y=11
2) x+y=6.50
Use 2) to isolate for a variable, for example:
3) y=6.50-x
Using 3), substitute it back into 1) to solve for x.
2x+2(6.50-x)=11
2x-2x+13=11
The x's cancel out, leaving you with:
13=11
This is not true, and therefore you cannot determine the prices of the taco salads or iced tea.
At 120 weeks, ...
• the table tells you plant A is 180 inches tall
• the function tells you plant B is 4·120/3 = 160 inches tall
• the graph tells you plant C is 360 inches tall.
The tallest plant is 360 inches tall; the shortest is 160 inches tall. Their difference in height is
... 360 in - 160 in = 200 inches
