He sold 32 small watermelons and 17 large watermelons.

Step-by-step explanation:

Let,

Small watermelons = x

Large watermelons = y

Cost of one small watermelon = $7

Cost of one large watermelon = $10

According to given statement;

x = y+15   Eqn 1

7x+10y=394   Eqn 2

Putting value of x from Eqn 1 in Eqn 2

7(y+15)+10y=394\\7y+105+10y=394\\17y=394-105\\17y=289\\

Dividing both sides by 17

\frac{17y}{17}=\frac{289}{17}\\y=17

Putting y=17 in Eqn 1

x=17+15\\x=32

He sold 32 small watermelons and 17 large watermelons.
