Mike has to spend $67.20 on his remodeling project.
Explanation:
6 ft = (4 + x) ft
4+x = 6
x = 6-4 = 2
Area 1:
S1 = 2 × (4+2)
= 2 × 6
= 12 ft²
Area 2:
S2 = 2 × (4+2)
= 2 × 6
= 12 ft²
The area of his kitchen is S1 + S2 = 12 + 12 = 24ft²
= 24 × 2.80
= $67.20
The image is given below for the area of the house.

The cost of one chapstick is $1 and one eyeliner is $2.
Step-by-step explanation:
Let,
Cost of one chapstick = x
Cost of one eyeliner = y
According to given statement;
3x+2y=7 Eqn 1
4x+5y=14 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 7
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one chapstick is $1 and one eyeliner is $2.
