Answer:

4 weeks

Explanation:

To calculate when Jayden and Noah will have the same amount of money saved, we need to write down an equation. Starting at $0, Jayden will save $2 per week, so their equation will be:

$0 + $2(week) = $

Noah starts with $10 and spends $0.50 per week, so his equation will be:

$10 - $0.50(week) = $

We want to find the week when the two equations are equal. So, we set them equal to each other and solve for "week":

$0 + $2(week) = $10 - $0.50(week)

$2.50(week) = $10

week = $10 ÷ $2.50

week = 4

So, Jayden and Noah will have the same amount of money saved after 4 weeks.

The same process applies for Maryam and Malak. Since Maryam starts with $m and saves $2 per week, her equation will be:

$m + $2(week) = $

Since Malak starts with $n and saves $1 per week, her equation will be:

$n + $1(week) = $

Setting the two equations equal to each other, we get:

$m + $2(week) = $n + $1(week)

$m - $n = $1(week)

So, Maryam and Malak will have the same amount of money saved after 1 week, assuming they have the same amount of money in their piggy banks when they start saving.
