Step-by-step explanation:
Let
be the number of paintings Ella sells for $
.
Let
be the number of paintings Ella sells for $
.
Profit made through $
paintings is ![50x](https://tex.z-dn.net/?f=50x)
Profit made through $
paintings is ![75y](https://tex.z-dn.net/?f=75y)
So,total profit is given by ![50x+75y](https://tex.z-dn.net/?f=50x%2B75y)
It is given that total profit is $![2975](https://tex.z-dn.net/?f=2975)
So,
..(i)
Given that the total number of prints is ![52](https://tex.z-dn.net/?f=52)
So,
..(ii)
using (i) and (ii),
![50x+75(52-x)=2975\\50x+3900-75x=2975\\25x=925\\x=37](https://tex.z-dn.net/?f=50x%2B75%2852-x%29%3D2975%5C%5C50x%2B3900-75x%3D2975%5C%5C25x%3D925%5C%5Cx%3D37)
![y=52-x=52-37=15](https://tex.z-dn.net/?f=y%3D52-x%3D52-37%3D15)
Answer:
For 100, your answer will be 102; For 898, your answer will be x; 100*x = 102*898 ... 102/x = 100/898 or x/102 = 898/100; x = 898*102/100 = 91596/100 = 915.96.

Let
R = Ralph's age
S = Sara's age
First statement is translated as:
S = 3R
Second statement is translated as:
S + 4 = 2(R + 4)
Use the first equation to be substituted into the second one in terms of R which is the one we are actually going to solve for Ralph's age.
Since S = 3R, then
3R + 4 = 2(R + 4)
3R + 4 = 2R + 8
3R - 2R = 8 - 4
R = 4 years old
X= -b over 2a = --6 over 2×1=3
