Answer:

14 weeks

Explanation:

Hello kenzieshirley, this question can be easily solved by setting up and equation.

To start we can say that in total Sam will be saving $3.50 every week

$1.50 + $2.50 = $3.50

Then we can set up a linear equation:

y = 3.50x

where y = total amount saved, x = weeks

then all we have to do is substitute $49 for y, as we want to know how many weeks, x, it will take to save up for Sam's phone.

49 = 3.5x

x=14

It will take Sam 14 weeks to save up $49

Hope this helps!
