or

Step-by-step explanation:
First write an equation : note key words like "per", "each" and "total".
7 per hour
5 each
6 hours
n= number of people
E= total earnings
total earnings
So:

$7 per hour plus $5 tips per person equals total earnings

S + l. = 34
11s + 21l= 514
-11s - 11l= -374
11s + 21l = 514
10l = 140
l = 20 long sleeve shirts
s + 20 = 34
s = 14 short sleet shirts
The solution to this is 5√(11)/11
Step-by-step explanation:
Add 75 to 12.55. the answer would be 87.55.
100+105=205
205-87.55=117.45
