To find the total cost of buying 4 computers with a discount, we can start by calculating the original cost without any discounts. The cost for 4 computers is given by:
\[
4d
\]
Since there is a $50 discount for each computer, the total discount for 4 computers is:
\[
4 \times 50 = 200
\]
Therefore, the total cost after applying the discount will be:
\[
4d - 200
\]
So, the algebraic expression describing the total cost of buying 4 computers is:
\[
4d - 200
\]
\[
4d
\]
Since there is a $50 discount for each computer, the total discount for 4 computers is:
\[
4 \times 50 = 200
\]
Therefore, the total cost after applying the discount will be:
\[
4d - 200
\]
So, the algebraic expression describing the total cost of buying 4 computers is:
\[
4d - 200
\]
