Answer:
the third one, y = 1/2x + 3
100%:2000$=4.5%:x$, x=90$. After 1st year I earned 90$, now I have 2090$.
100%:2090$=4.5%:x$, x=94.5$. After 2nd year I earned 94.5$ more, now I have 2184.05$.
100%:2184.05$=4.5%:x$, x=98.28$. After 3rd year I have 2282.33$.
100%:2282.33$=4.5%:x$, x=102.71$. After 4th year I have 2385.04$.
100%:2385.04$=4.5%:x$, x=107.33$. After 5th year I have 2492.37$.
So I need 6 years to earn 495$.
30 bags of flour + 4 bags of sugar = 42.6 kg
each bag of sugar weighs 0.75 kg
each bag of flour weighs x kg = ?
If you would like to know what is the weight of each bag of flour, you can calculate this using the following steps:
30 * x + 4 * 0.75 kg = 42.6 kg
30 * x + 3 kg = 42.6 kg
30 * x = 42.6 kg - 3 kg
30 * x = 39.6 kg /30
x = 39.6 kg / 30
x = 1.32 kg
Result: Each bag of flour weighs 1.32 kg.
