Question

i need some help please

Answer 1

first calculate the tax

8.5% of 75 is (8.5/100)*75

then add this back to the original bill 75 to get the total price w/ tax

Answer 2

so 6.37 + 75.00?

Answer 3

close, if you multiply (8.5/100)*75 you get 6.375 which rounds up to 6.38

so 6.38 + 75.00 yes

Answer 4

alright, can you help with a bit more?

Answer 5

I'll do my best

Answer 6

almost ^^

a percent tells you how much of the part is out of the whole thing

so part/whole not whole/part

Answer 7

so 50 percent/100 = 1 part out of 2 whole, for example

Answer 8

almost

the instructions say to round the bill up to the nearest dollar first

so you would calculate 0.15*38 not 0.15*37.75

Answer 9

ah, alright

Answer 10

so $5.07?

Answer 11

close, 5.70, watch the decimal point

Answer 12

good

Answer 13

A+ good

Answer 14

almost

it's asking what percent of the total bill you'd pay

so you'd add 100% to represent the original bill, plus the 9.5% tax

Answer 15

so C?

Answer 16

100% + 9.5% = 109.5%

Answer 17

ehh Finance isn't really my subject but I believe that's correct

Answer 18

oh, well darn..

Answer 19

well from a purely mathematical standpoint, you'd divide total miles/your car's mpg to get the total number of gallons, then multiply by the price per gallon

since this is a personal finance question I would imagine they would want you to set your budget above that, idk how much though

Answer 20

hm..

Answer 21

idk if you're using a textbook/online lecture or whatever, but if you can try to find a formula or something that tells you how much extra to budget that would be good

Answer 22

plugging the numbers in gives me about 128 but in terms of creating a budget you would want to exceed that a bit

Answer 23

I don't want to mislead you because I really don't know what formula should be applied to FICA

however instinctively it seems you would just calculate 7.65% of 36590 and subtract that from 36590

Answer 24

@Vocaloid

Answer 25

yup good

Answer 26

close

it starts on day 1 not day 0 so the appropriate equation would be

8500(1.1)^(n-1)
(this way, when you plug in n = 1 you end up with 8500)

when you plug n = 30 into this you get 134836 not 148320

Answer 27

similar logic to the last problem. if you want n = 1 to equal 8 you have to change the exponent to (n-1) instead of n

the way it's written right now, n= 1 will give 4 not 8

Answer 28

so C?

Answer 29

yes
