<h2>Answer:37 paintings of $50 and 15 paintings of $75</h2>

Step-by-step explanation:

Let x be the number of paintings Ella sells for $50.

Let y be the number of paintings Ella sells for $75.

Profit made through $50 paintings is 50x

Profit made through $75 paintings is 75y

So,total profit is given by 50x+75y

It is given that total profit is $2975

So,50x+75y=2975      ..(i)

Given that the total number of prints is 52

So,x+y=52      ..(ii)

using (i) and (ii),

50x+75(52-x)=2975\\50x+3900-75x=2975\\25x=925\\x=37

y=52-x=52-37=15

Answer:

<h2>37 small prints and 15 large prints</h2>

Step-by-step explanation:

       Ella sold a total of 52 prints for a total of $ 2,975. Small prints cost $ 50 and large prints cost $ 75.

       Let us denote the number of small prints sold by x and the number of large prints sold by y.

       Total number of prints sold = x+y=52        -(i)

       Total amount = 50x+75y=2975                        -(ii)

Multiplying first equation with 50 and subtacting it from second equation,

       50x+75y-50x-50y=2975-50(52)\\25y=375\\y=15\\x=37

∴ Ella sold 37 small prints and 15 large prints.
