There are 156 rows of trees altogether.

Step-by-step explanation:

Given that for every 11 rows of Red delicious , they plant 3 rows of Royal Gala.

Thus for 1 row of Royal Gala there would be 11/3 rows of Red delicious.

Number of rows of Royal Gala=18

[tex]corresponding\ number\ of\ Red\ delicious\ = 11/3 \times 18=11\times 6=66[/tex]

For 11 rows of red delicious,they plant 7 rows of yellow delicious.

Thus for 1 row of Red delicious,there would be 7/11 rows of yellow delicious.

For 66 rows of red delicious there would be

[tex]7/11\times66=7\times 6=42 rows\ of\ yellow\ delicious[/tex]

For 11 rows of red delicious,they plant 5 rows of Braeburn

for 1 row of red delicious,they would plant 5/11 rows of Braeburn.

For 11 rows of red delicious,they would plant

[tex]5/11\times 66=5\times 6=30\ rows\ of\ braeburn[/tex]

Total rows of trees=66+42+30+18=156
