Use numerals instead of words. If necessary, use / for the fraction bar. This data set represents the number of cups of coffee sold in a café between 8 a. m. and 10 a. m. every day for 14 days. {10, 9, 6, 12, 4, 6, 7, 8, 15, 14, 12, 9, 10, 5}. The difference of the values of the first and third quartiles of the data set is

you can't solve x because it is 2 linear equation and you only have one equation

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

the correct answer is c
