WILL GIVE BRAINLIEST THINGY. At the hardware store, a pound of 3-inch nails costs $1.75. Carol wants to graph the relationship between number of pounds and total cost. What should be the slope of Carol's graph and why? A) The slope is 3, because there are 3 nails per pound.

B) The slope is 3, because $3.00 is the cost per pound.

C) The slope is 1.75, because $1.75 is the cost per nail.

D) The slope is 1.75, because $1.75 is the cost per
pound.

It should be D) Slope of 1.75

Step-by-step explanation:

Choice D.

Step-by-step explanation:

With each purchase of a pound of nails (the actual product), the cost increases by $1.75 every time. Since you are buying a pound of nails every time, rather than a single one, the cost stays at $1.75, but if you double or triple that, the price increases by that amount ($1.75). So if you were to buy it three times, it would go like $1.75 • 3, or $1.75 + $1.75 + $1.75.
