A $800 tv is on sale for 40% off. What is the sale price? What is the final price after paying 6% tax?
geniusboy [140]

Answer:

Sale price is $480

Final Price is $508.80

Step-by-step explanation:

$ saved = Original Price x Discount % / 100

S =800 x 40/100

S = 32000 / 100

S = $320

Subtract 320 from 800 and get $480.

Multiply $480 by 0.06 to get $28.80 then add $28.80 to $480 to get $508.80

A phone company offers two monthly plans. Plan A costs $11 plus an additional $0.11 for each minute of calls. Plan B costs $27 p
irina1246 [14]

Solution:

Let x represent a number of calling minutes. According to the problem, we want:

11\text{ + 0.11 x = }27\text{ + 0.07 x}

now, putting the similar terms together, we obtain:

0.11\text{ x - 0.07 x = 27 -11 }

this is equivalent to:

0.04x\text{ = 16}

now, solving for x, we get:

x\text{ = }\frac{16}{0.04}\text{ = 400}

then, the correct answer for the first question is:

400 minutes is the number of minutes the two plans cost the same

now, for the second question, we can replace the above value (400 minutes) into the following equation:

11\text{ + 0.11(400) = }55

so that, the correct answer for the second question is:

$55 is the cost when the two plans cost the same
