25 surf boards and 19 puddle boards were rented.
Step-by-step explanation:
Given,
Rent of each surf board = $45
Rent of puddle board = $60
Total boards rented = 44
Total amount = $2265
Let,
x represent the number of surf boards rented
y represent the number of puddle boards rented
According to given statement;
x+y=44 Eqn 1
45x+60y=2265 Eqn 2
Multiplying Eqn 1 by 45
Subtracting Eqn 3 from Eqn 2
Dividing both side by 15
Putting y=19 in Eqn 1
25 surf boards and 19 puddle boards were rented.
