B) 5C + 12A = 780

7A = 280

Number of Adults = 40

5C = 780 - 40*12

Vikentia [17]

Step-by-step explanation:

rc = planted rows of carrots

rt = planted rows of tomatoes

h = number of hours

rc = 4h + 1 (starting with 1 already finished row there will be 4 additional rows every hour)

rt = 3h + 8 (staying with 8 already finished rows there will be 3 additional rows every hour).

when will they have planned the same number of rows ?

when rc = rt, of course.

so,

4h + 1 = 3h + 8

h = 7

4×7 + 1 = 28 + 1 = 29 rows

after 7 hours Quincy and his mom will each have planted 29 rows of vegetables.
