Answer:
6.25 kg cement, 7.5 L water
Step-by-step explanation:
2.5 kg cement / 4 kg sand = x kg cement / 10 kg sand
x = 6.25
3 L water / 4 kg sand = y L water / 10 kg sand
y = 7.5
Answer:
25 months
Step-by-step explanation:
when the rent, y = 0, we have,
y = -200.22x + 5014.20
y = 0
0 = -200.22x + 5014.20
200.22x = 5014.20
x = 5014.20 ÷ 200.22
x = 25.0434
x = 25(appx.)
