Kate: 1250 ≥ 525+25x
25x ≥1250 -525
25x ≥ 725
x ≥ 725 / 25
x≥ 29 weeks
Rebecca: 1350 ≥ 510 + 30x
30x ≥ 1350 - 510
30x≥ 840
x≥ 840 / 30
x≥28 weeks

See each answer bolded below
Step-by-step explanation:
1. Area of the rectangle is 20 * 30 = 600
Area of the 6 circles is 6(25pi)
150pi/600 = 0.7854
1 - 0.7854 = 0.2146
convert to percentage 21.46%
2. 6/16 -> 3/8
Roughly 38% (37.5)
3. 10/24 = 0.41666666667 or 0.4167
41.66
roughly 42%
4. 12/36 -> 1/3
33.3333
