Jeremy has a summer job, where he earns $8 per hour. His employer always rounds up to the nearest quarter of an hour. For example, if Jeremy works 5 hours and 10 minutes, he is paid for 5.25 hours. If f(h) is a function that represents the amount Jeremy earns for working h hours, which values are in the domain of f? Select ALL that apply. 4.5 4.8 5.1 5.75 6.0

answer: 12

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
