To evaluate the expression 7(l + 2w), we substitute l = 5 and w = 2.
7(5 + 2(2))
= 7(5 + 4)
= 7(9)
= 63
So, the cost for the garden is $63.
To find the cost of a fence for Mr. Rodriguez's garden, we can use the formula 7(l + 2w), where l is the length and w is the width of the garden.
Given that the length is 5 yards and the width is 2 yards, we can substitute these values into the formula: 7(5 + 2*2).
Simplifying the expression inside the parentheses, we have: 7(5 + 4).
Adding the numbers inside the parentheses, we get: 7(9).
Finally, multiplying 7 by 9, we find that the cost for a garden with a length of 5 yards and a width of 2 yards is $63.
Therefore, the correct answer is $63.
To evaluate the expression 7(l + 2w) where l is the length and w is the width of the garden, we substitute the given values of l = 5 yards and w = 2 yards into the expression.
So, we have 7(5 + 2*2) = 7(5 + 4) = 7(9) = 63.
Therefore, the cost for a garden that has a length of 5 yards and a width of 2 yards is $63.
