Larry is paid 8.5% of all sales plus 4.25% of all sales over $6800. find larry's gross pay from total sales of $12,300?

$1279.25

Step-by-step explanation:

The first $6800 is multiplied by .085 to get the 8.5% they earned. This equals $570. After that, the remaining money is multiplied by .1275 to get the 8.5%+4.25%. This leaves you with $5500x.1275. This equals 701.25. $701.25+$570=$1279.25. Hope this helps :)

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
