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 width of 2 yards.
Options:
$63
$98
$39
$16
To find the cost for a garden with a length of 5 yards and a width of 2 yards, we substitute l = 5 and w = 2 into the expression 7(l + 2w):
7(5 + 2(2)) = 7(5 + 4) = 7(9) = 63
Therefore, the cost for a garden with a length of 5 yards and a width of 2 yards is $63.
The correct answer is $63.
