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
4/5.
___
Steps: Find a common denominator - 20. 4 x 5 = 20 3 x 5 = 15 --- 15/20
5 x 4 = 15 -- 4 x 4 =12 ---- 16/20
16/20 is bigger than 15/20.
So, 4/5 is bigger.
