And it is a correct solution
Answer:
Dimension of room = 18 foot x 18 foot
Step-by-step explanation:
Let the square room is of side a foot,
The cost of re-finishing the hardwood floors is $2.25 per square foot and the cost of purchasing and installing the new baseboards $14.5 per linear foot
Total cost is $1773.
Cost for re-finishing the hardwood floors = Area x 2.25
Area = a²
Cost for re-finishing the hardwood floors = 2.25 a²
Cost of purchasing and installing the new baseboards = Perimeter x 14.5
Perimeter = 4a
Cost of purchasing and installing the new baseboards = 4a x 14.5 = 58 a
Total cost = Cost for re-finishing the hardwood floors + Cost of purchasing and installing the new baseboards
1773 = 2.25 a² + 58a
2.25 a² + 58a - 1773 = 0
a = 18 or a = -43.77(not possible)
Dimension of room = 18 foot x 18 foot
Answer:
Hotdog costs $5.35 each and hamburger costs $0.18 each
Step-by-step explanation:
The difference in price between the two is the cost of 5 hotdogs.
So, $56.25 - $29.50 = $26.50
I hotdog would cost $26.50/5 = $5.35
Substituting the cost of one hotdog,
10($5.35) + 15ham = $56.25
$53.50 + 15 ham = $56.25
15 ham = $56.25 - $53.50
15 ham = $2.75
So, 1 ham = $2.75/15
= $0.18
