Gabrielle wants to put a border around her garden. It costs $1.50 per yard for the materials. Use 1.50(2l+2w), where l is the length and w is the width of her garden, to find the cost for a garden that has a length of 4 yards and a width of 3 yards.(1 point)
We can substitute the values for length and width into the formula to find the cost.
The length is 4 yards and the width is 3 yards.
So, replacing l with 4 and w with 3 in the formula, we get: 1.50(2*4+2*3)
Simplifying this gives us: 1.50(8+6)
Further simplification gives us: 1.50(14)
Finally, multiplying 1.50 by 14 gives us the cost for the garden, which is $21. Answer: \boxed{21}.
To find the cost of putting a border around Gabrielle's garden, we can use the formula: 1.50(2l + 2w), where l is the length and w is the width of the garden.
Given that the length of the garden is 4 yards and the width is 3 yards, we can substitute these values into the formula.
Cost = 1.50(2(4) + 2(3))
Simplifying the equation inside the parentheses, we have:
Cost = 1.50(8 + 6)
Adding the numbers inside the parentheses, we get:
Cost = 1.50(14)
Now, we can multiply 1.50 by 14:
Cost = 21
Therefore, the cost for Gabrielle to put a border around her garden with a length of 4 yards and a width of 3 yards is $21.
To find the cost of a border around Gabrielle's garden, we can use the formula 1.50(2l+2w), where l is the length and w is the width of the garden.
In this case, the length (l) is given as 4 yards and the width (w) is given as 3 yards. Now we can substitute these values into the formula:
Cost = 1.50(2 * 4 + 2 * 3)
First, we can simplify the parentheses by performing the calculations:
Cost = 1.50(8 + 6)
Now, we add the numbers inside the parentheses:
Cost = 1.50(14)
Finally, we multiply 1.50 by 14 to find the total cost:
Cost = $21
Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards is $21.
