<span>Multiply the length and width together to get the total required area - 5*8 = 40. Now each tile covers 3 inches and you need to cover 40 feet, so convert feet into inches by multiplying 40 by 12 (480). Now divide 480 (desired area) by 3 (how much each tile covers) to get 160 - the amount of tiles you'll need.
Sorry, didn't realize I didn't post it as an answer. But no problem!</span>
Answer:
32 magazines
Step-by-step explanation:
If x is the number of subscriptions in December, then the number in January is x-7.
The relationship between the average price of magazines in the two months is ...
80/(x-7) -80/(x) = 0.70 . . . . . . . . .Jan price - Dec price = 0.70
80(x) -80(x -7) = 0.70(x)(x-7) . . . . multiply by the denominators
0.7x^2 -4.9x +560 = 0 . . . . . . . . put in standard form
x^2 -7x +800 = 0 . . . . . . . . . . . . . divide by 0.7
(x -32)(x +25) = 0 . . . . . . . . . . . . . factor
The product is zero when one of the factors is zero. x=32 or -25. The sensible solution for this problem is x=32.

Answer:
The location offering the better price is The Framers. It is cheaper by $1.35
Step-by-step explanation:
I've Been Framed:
50% of $115 = $57.5
10% of $57.5 = $5.75
$57.5 - $5.75 = $51.75
Total: $51.75
The Framers:
30% of $120 = $36
$120 - $36 = $84
40% of $84 = $33.6
$84 - $33.6 = $50.4
Difference: $1.35
