Question

which expression could represent the total cost of the nuts? a 4.75(x - 20) b 4.75x c 4.75(20 - x) d 4.75(20 + x)

Explanation:

Since we don't know any information about the number of nuts (let's assume the number of nuts is $x$) and the cost - per - nut is $4.75$.
The total cost of nuts is calculated by multiplying the cost per nut by the number of nuts.

Step1: Recall cost - calculation formula

Total cost = Cost per unit×Number of units

Step2: Substitute given values

If cost per nut is $4.75$ and number of nuts is $x$, then total cost = $4.75\times x=4.75x$

Answer:

B. $4.75x$
