Let price of a basket ball be b
Let price of a vollyball be v.
Given price of 5 basketball and 6 vollyball is 325 dollars
or 5b + 6v = 325 -----------------------(1)
Also, cost of single basketball costs 10 more than volleyball.
or b= v+10 -------------------------(ii)
Substituting the value of (ii) in (i) we get:
5(v+10) + 6v = 325
or 5v + 50 +6v = 325
or 11v +50 =325
or 11v = 325-50
or 11v = 275
or v = 275/11 = 25
Now putting the value of v in equation (ii) we get:
b = v+10
or b = 25+10 = 35
So cost of a single basketball is $35.
And cost of a single volleyball is $25
