Answer:

27% of change

Step-by-step explanation:

If you get a calculator type in 400 multiplied 73% you get $292. Its not the exact answer because there is no exact answer for this but..... There is always tax you have to pay for an item and so here Anthony would have to pay $3 for tax.

If 27% is not one of the answers the other answer that is possible is 30% and you would get a total of $280 and pay $15 for taxes.

Hope this helps :)

Help me please !!!!!!
Mrac [35]

Answer:

z = -44

Step-by-step explanation:

3/4 (x - 8) = 4

3(x - 8) = 16

3x - 24 = 16

3x = 40

x = 40/3

4 - 2x = -5x - z

4 = -3x - z

z = -3x - 4

z = -3(40/3) - 4

z = -40 - 4

z = -44

PilotLPTM [1.2K]

Answer:

D

Step-by-step explanation:

The interest is compounded annually, which means that interest from the previous year earns you even more money next year.

It should be obvious that after one year Alexis will have

$475 + $475 * 1.25% = $475 * 100% + $475 * 1.25% =

= 101.25% * $475 = 1.0125 * $475

Then, next year she would have

1.0125 * $475 + (1.0125 * $475) * 1.25% =

= (1.0125 * $475) * 1.0125 = 1.0125^2 * $475

See the pattern?

Alexis will have $475 * 1.0125^x after x years.

faltersainse [42]

Answer:

Part A: $13.76 saved. Part B: $55.04

Step-by-step explanation:

Part A: Set a proportion up d/68.8 = 20/100

100·d=100d 68.8·20=1376

100d/100 cancels out

1376/100=13.76 so $13.76 was saved

Part B: 68.80-13.76= 55.04 so $55.04 was what he paid.
