Answer:
L = 5S - 3
length of long side = 134.5 ft
length of short side = 27.5 ft
Step-by-step explanation:
L = 5S - 3
2L + 2S = 324 (keyword: enclose)
2(5S - 3) + 2S = 324
10S - 6 + 2S = 324
12S = 324 + 6 = 330
Thus S = 330/12 = 27.5 ft
Thus L = 5(27.5) - 3 = 134.5 ft
His new apartment will cost him "10% more" than what he is paying currently.
100% = current rent
10% = the extra amount he will pay for his new apartment
100% + 10% = new rent
100% + 10% = 110%
Now convert the percent into a decimal by moving the % sign two places to the left and make the % sign into a decimal point.
110% = 1.10
500 * 1.10 = 550
So, he will pay a rent of $550 for his new apartment.
