Answer: c = d + 6x

Step-by-step explanation: We shall first assign letters to all variables, hence let the cost be c, the deposit be d, and the installments be x.

The payment for the \$335 laptop was settled by an initial deposit of \$50, and then six equal monthly installments of \$47.5

With that the relationship between cost and payment becomes,

335 = 50 + (6 x 47.5)

Using the variables above, the relationship can be written out as an equation thus;

c = d + 6x

A = b + 6c

Step by step explanation:

The question here says that Cole bought a new laptop for \$335. He makes a down payment of \$50 and pays the rest in 6 equal monthly payments. What equation represents the relationship between the cost of the laptop and Cole's payments

Let's assume that the cost of the laptop is "a", the initial payment to be "b" and the installments to be "c"

The initial fee paid for the laptop was 50 and the rest was paid over a period of 6 months.

335 - 50 = \$285 was the remaining amount paid in installments

285/6 = \$47.5 was paid over 6 months period

With that in mind, the relationship between cost and payment is:

335 = 50 + (6 x 47.5)

A = b + (6 x c)

A = b + 6c
