Solving (b): Cost of T
Substitute 16 for W
Hence, each tree costs $67
Answer:
14
Step-by-step explanation:
Given that:
Cost of purchase and installation = 5323.50
Cost per window = 230.25
Cost of installation = 2100
Hence,
Total purchase cost of windows alone :
5323.50 - 2100 = 3,223.50
Therefore, the number of windows purchased is :
(Total purchase cost of windows alone / price per window)
(3,223.50 / 230.25)
= 14
Hence, 14 windows was purchased

Answer:
A literal equation is an equation that consists of multiple variables or letters.
A linear equation is an equation that consists of one variable
Step-by-step explanation:
Literal EX:
a = 1/2h(a + b)
ax + b = c
u = ak/b
Linear EX:
5(3a + 8) = 12a
4a = 8
11(3a - 18) = 12a
4/81 (?)
not sure if that is 100% correct
