Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.
<u>Step-by-step explanation:</u>
We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :
<u>Rory:</u>
Number of strokes per hole = 
<u>Alicia:</u>
Number of strokes per hole = 
<u>Rickie:</u>
Number of strokes per hole = 
∴ Golfer had the lowest number of strokes per hole is <u>Alicia </u> = 4.
First write an equation system based on the problem
We can write "<span>Bread and sugar cost 110 together" as
</span>∴ b + s = 110
We can write "<span>bread cost 100 more than sugar" as
</span>∴ b = 100 + s
<span>
Second, solve the equation system by subtitution method
Subtitute b with (100+s) in the first equation, and we'll find the value of s
b + s = 110
(100 + s) + s = 110
100 + 2s = 110
2s = 110 - 100
2s = 10
s = 10/2
s = 5
The cost of the sugar is 5</span>
