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.(1 point)

I just took the test and the answer is $63 because in the order of operations, multiplication comes before addition.
To find the cost, we need to substitute the given values for length (l = 5 yards) and width (w = 2 yards) into the equation 7(l + 2w).
Substituting the values, we have 7(5 + 2(2)).
Simplifying the expression inside the parentheses, we have 7(5 + 4).
Adding the values inside the parentheses, we have 7(9).
Multiplying 7 by 9, we get 63.
Therefore, the cost for a garden that has a length of 5 yards and a width of 2 yards is $63.
So, the correct answer is $63.
To find the cost of the fence for Mr. Rodriguez's garden, we need to evaluate the expression 7(l + 2w), where l is the length of the garden and w is the width of the garden.
Given that the length is 5 yards and the width is 2 yards, we substitute these values into the expression:
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 would be $63.
The correct answer is: $63
To find the cost of the fence around the garden, we need to determine the perimeter of the garden. The formula for the perimeter of a rectangular garden is P = 2l + 2w, where l is the length and w is the width.
Given that the length of the garden is 5 yards and the width is 2 yards, we can substitute these values into the formula:
P = 2(5) + 2(2)
P = 10 + 4
P = 14 yards
Next, we need to find the cost of the fence materials, which is $7 per yard of perimeter. We can multiply the perimeter (14 yards) by $7:
Cost = 7 * 14
Cost = $98
Therefore, the correct answer is $98.
