Amount of green grapes bought = 
pounds
Amount of red grapes = 
pounds
Let us assume that both the grapes have same price per pound.
Total quantity of grapes = 
=
= 3.7 pounds
Price of 1 pound of grapes = $2.99
So price of 3.7 pounds = 
=11.063
Price is $11.063
Hence, Lexi spent less than $12.

Answer:
x = 3
Step-by-step explanation:
The standard form of the equation of a line is ...
ax + by = c
For two points (x1, y1) and (x2, y2), this can be written as ...
(y2-y1)x -(x2-x1)y = (y2-y1)x1 -(x2-x1)y1
(7-(-6))x -(3-3)y = (7-(-6))3 -(3-3)(7)
13x - 0y = 13·3
Standard form requires no common factors among the constants, so ...
x = 3
