nalin [4]

Let s be the son's age 15 yeasr ago and m the mother's age that year.

$s = \dfrac{m}{3}$

We also know that:

$m = s+30$

Plotting vallues:

$s = \dfrac{m}{3}\\\\\\3s = s+30\\\\2s = 30\\\\s = 15\\\\m = 45$

Remember that they were that age 15 years ago.

Answer:

You will need to buy 5 1.50lb bags of sugar to make your recipe.

Step-by-step explanation:

This problem can be solved by consecutive rules of three.

A large recipe calls for 3.18kg of sugar. Your bags of sugar are measured in pounds (lb). Remembering that 1kg=2.20462lb

How many lbs of sugar you will need to buy?

1 kg - 2.20462lb

3.18 kg - x lb

$x = 3.18*2.20462$

$x = 7 lb$

How many 1.50lb bags of sugar will you need to buy to make your recipe?

1 bag - 1.50 lb

x bags - 7 lb

$1.5x = 7$

$x = \frac{7}{1.5}$

$x = 4.67$

You will need to buy 5 1.50lb bags of sugar to make your recipe.
