The initial dimenssions of the park lot are:
length: 140 ft
width: 90 ft
initial area: 140 * 90 = 12,600 ft^2
Area increased 29% = 12,600 * 1.29 = 16,254 ft^2
width of the strips: x
New length: 140 + x
New width: 90 + x
New area: (140+x)(90+x) = 16,254
Solution of the equation:
12600 + 230x + x^2 = 16254
=> x^2 + 230x - 3654 = 0
Use the quadratic formula.
x = {-230 +/- √[ 230^2 - 4*1*(-3654) ]} / 2 =
x = 14.92
The other solution is negative so it is discarded.
Answer: 15 ft
Based on the information, the price per soda is 3 dollars. <u>Option D</u>. $3.00 per soda is the correct answer.
<u>Step-by-step explanation</u>:
<u>The given table is</u>:
Number of sodas sold Total money collected
0 $0.00
2 $6.00
5 $15.00
9 $27.00
10 $30.00
From the information given in table, it can be determined that the cost of 2 sodas is $6.
cost of 1 soda = Total cost / number of sodas = $6 / 2 = $3
Similarly,
The cost of 5 sodas is $15, then the cost of one soda = $15 / 5 = $3
The cost of 9 sodas is $27, then the cost of one soda = $27 / 9 = $3
The cost of 10 sodas is $30, then the cost of one soda = $30 /10 = $3
5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
