To solve this problem, we must isolate b from the rest of the problem.

a= -bc

Firstly, divide -bc by c

a/c=-bc/c

The c on -bc cancels out

a/c=-b

Transfer the negative to he other side of the equation

b= -a/c

Deacon wants to order DVDs. Each DVD costs $12.95, and he must pay a shipping and handling fee of $4.95 for the entire order. De

Aneli [31]

Answer:

$12.95x + 4.95 \leq 75$

Step-by-step explanation:

Given

Represent number of DVDs with x

$Each\ DVD = \$12.95$

$Handling\ Fee = \$4.95$

$Budget = \$75$ (at most)

Required

Represent as an inequality

If $Each\ DVD = \$12.95$

x DVD would cost:

$x\ DVDs = 12.95 * x$

$x\ DVDs = 12.95x$

So, to make an order of x DVDs, Deacon will pay for

x DVDs and Handling Fee

So:

$Payments = 12.95x + 4.95$

Recall that his budget is at most $75

This implies that: $\leq 75$

So, the relationship between his payment and budget is:

$12.95x + 4.95 \leq 75$
