Mr. Rodriguez has a vegetable garden that borders his house. He wants to put a fence around it. It costs $7 per yard for the materials. Evaluate 7(l + 2w) , where l is the length and w is the width of his garden, to find the cost for a garden that has a length of 5 yards and a width of 2 yards.
To evaluate the expression, substitute l = 5 and w = 2 into the expression 7(l + 2w):
7(5 + 2*(2)) = 7(5 + 4) = 7(9) = <<7*(9)=63>>63
The cost of putting a fence around a garden with a length of 5 yards and a width of 2 yards is $63. Answer: \boxed{63}.
