Answer:

I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)

<u><em>The variable is the number of shirts she bought or x</em></u>

and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>

in the solve spot put

<em><u>(375+50) divided by (15+2)=x</u></em>

<em><u>425 divided by 17=x</u></em>

<em><u>x=25</u></em>

Then your answer would be <u><em>25</em></u>

Step-by-step explanation:

first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.
