Well after doing your multiplication, you can place your decimal point by knowing that from estimation the answer is around 20.
So you can place your decimal point after the first two digits from the left.
Answer:
Step-by-step explanation:
m = 5 ; (3, -4)
y - y₁ = m (x - x₁)
y - [-4] = 5 (x - 3)
y + 4 = 5x - 15
y = 5x - 15 - 4
y = 5x - 19
Use the app Desmos it’s a graphing calculator! Or you can go to y= if you have a TI-84 plus calculator
The cost of delivering an item that weighs 4/5 of a pound?$21.60.
<h3>How to find the delivery cost?</h3>
Let x = the number of pounds
Thus, we can say that;
Cost = 25x * 1.08
Since we want to find the cost of delivering an item that weighs 4/5 of a pound, the we will put 4/5 for x to get;
Cost = (25 * 4/5) * 1.08
Cost = 20 * 1.08
Cost = 21.6
The delivery cost would be $21.60.
