Answer:
So W is going to stand for width and L is going to stand for length.
L= 2W+6
78=2L + 2W
Those are the two equations you will use. So plug in L=2W+6 into the other one and solve.
78= 4W+12 +2W
(simplify)
78=6W+12
(-12 from both sides)
66=6W
(divide by 11)
W=11
Replug W into your equation to find L.
L=22+6
(simplify)
L=28
I hope this is right
Step-by-step explanation:
Option 2 because in option one 7.5% of $300 is $22.50 so more would be put in if he chose the second option

|-10| + |28|
= 10 + 28
= 38
Answer
changed 38 degrees F
