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.
