Answer 1

Answer: so 5 dollar is autpay
so total pay=(payperhour) times (hoursworked) +tip/autopay
total pay needed=75
autopay=5
pay per hour=10 dolllar per hour or 10
replace payperhour with 10
replace hoursworked with h
subsitute and solve
75=10 times h+5
subtract 5 from both sides
70=10 times h
divide both sides by 10
7=h

she needs to work at least 7 hours

a.
inequality is she needs to make at least 75
at least is <
so the inequality is
75<10h+5 or
10h+5>75

b. we solved the inequality above
answer is
hours>7
at leas 7 hours

Answer 2

Answer: $10(7+x)=75$ she charges $10 an hour = $10
$10(7+5x)=75$ she needs $75 + $5 tip = 5t 10*7=70 + 5 = 75

she needs to babysit 7hours in all..
she charges 10$ an hour , if she dose 7 hours she will have 70$ but there is an automatic tip of 5$ soo 70 + 5 = 75

dose this help?

Original price: $32 ;Markup: 12.5% ; What is the retail price

Answers

If you would like to know what is the retail price, you can calculate this using the following steps:

original price ... $32
markup ... 12.5%

12.5% of $32 = 12.5% * 32 = 12.5/100 * 32 = $4
$32 + $4 = $36

Result: The retail price is $36.

It think 36$ but I am not 100 percent sure, I learned how to do this but I was taught to find the percentage up the markup.
