Answer:
Stefan originally spent $110
Stefen made $33 by selling the bicycle and helmet to jin.
Step-by-step explanation:
let ,
the original cost of bicycle and helmet for Stefan be 'x'
now,
total cost for Jin of bicycle and helmet = 126 + 17
= 143
also, total cost for Jin = 130% of original cost for Stefan
⇒ 143 =
⇒ x = 110.
hence,
profit made by Stefan = total cost for Jin - original cost for Stefan
= 143 - 110
= 33
Given:
Distance between two buildings = feet apart.
Distance between highway and one building = feet.
Distance between highway and second building = feet.
To find:
The standard form of the polynomial representing the width of the highway between the two building.
Solution:
We know that,
Width of the highway = Distance between two buildings - Distance of both buildings from highway.
Using the above formula, we get the polynomial for width (W) of the highway.
Combining like terms, we get
Therefore, the width point highway is .
