Answer 1

Answer:

48. Expression 1a: 1.05($16x)

Expression 2a: 1.07($18x)

Expression 1b: 0.9 × [1.05($16x)]

Expression 2b: [1.07($18x)] - $20

0.9 × [1.05($16 × 15)]

0.9 × [1.05($240)]

0.9 × $252

$226.80

[1.07($18 × 15)] - $20

[1.07($270)] - $20

$288.90 - $20

$268.90

$226.80 + $268.90 = $495.70

Answer: $495.70

47. 1 = 30

2.5 = 75

30 × 75 = 2,250

15^2 = 225

Pi × 225 = 706.86

706.86 + 2,250 = 2,956.86

Answer: 2,956.86 square feet

30 × Pi = 94.25

75 × 2 = 150

94.25 + 150 = 244.25

Answer: 244.25 feet
