So you subsitute 275 for n in the equation

becaue the question says 'let n represent the number of text messages'
so .15(n-250)+5=.15(275-250)+5
so we do the stuff in the parenthasees () first so .15(25)+5

multiply by .15 or 15/100 so 
and you get 3.75
3.75+5
you add 5 and get 8.75

The cloth shop has announced a reduction in price by 25%. How many shirts priced at Rs 28 should buy to avail a total reduction
Drupady [299]

Answer:

At least 6 shirts should be brought to avail a total reduction of Rs 40.

Step-by-step explanation:

The marked price of each shirt = Rs 28

Discount offered = 25%

So, 25% of marked price  28 = \frac{25}{100}  \times 28 = 7

⇒Reduction on each shirt is Rs 7

Now, total amount reduction needed = Rs 40

So, number of shirts purchased = \frac{\textrm{Total reduction needed}}{\textrm{Reduction on each shirt}}

= 40  Rs /7  Rs  =  5. 71  ≈  6

So, at least 6 shirts should be brought to avail a total reduction of Rs 40.

Simplify to create an equivalent expression 2-6(-5t+1)
Mariulka [41]

Answer:

30t - 4

Step-by-step explanation:

Remember to follow PEMDAS. First, distribute -6 to all terms within the parenthesis:

2 -6(-5t + 1) = 2 + (-6 * -5t) + (-6 * 1)

2 + (30t) + (-6) = 2 + 30t - 6

Simplify. Combine like terms:

2 + 30t - 6 = 30t + (-6 + 2) = 30t - 4

30t - 4 is your answer.

Vaughn Manufacturing has three product lines. Its only unprofitable line is Corn Nuts, the results of which appear below for 201
elena-14-01-66 [18.8K]

Answer: The relevant costs are $18000 in the decision to eliminate this product line.

Step-by-step explanation:

Since we have given that

Sales = $1530000

Variable expenses = $1040000

Fixed expenses = $600000

Net loss = $110000

If product line is eliminated, 30% of the fixed expenses can be eliminated.

So, it becomes,

30% of $600000 is given by

0.3\times 600000\\\\=\$18000

Hence, the relevant costs are $18000 in the decision to eliminate this product line.
