Question

A store sells almonds for $4 per pound. Write an equation to find the total cost, y, of buying x pounds of almonds, using the form y = kx.​

Answer 1

The equation to find the total cost, y, of buying x pounds of almonds is:

y = 4x

Here, k is the cost per pound of almonds, which is $4 in this case, and x represents the number of pounds of almonds purchased. Multiplying the cost per pound ($4) by the number of pounds purchased (x) gives the total cost (y) of buying x pounds of almonds.
