Answer:
Li already subtracted 40 rows of 7 from the total. To figure out how many more rows of 7 Li can make in the array, we need to find the remaining value after subtracting the 40 rows from 294.
294 - (40 * 7) = 294 - 280 = 14
After subtracting 40 rows of 7 from 294, the remaining value is 14. Now, we need to determine how many more rows of 7 can be made with this remaining value.
To divide 14 by 7, we divide the value 14 by the divisor 7:
14 ÷ 7 = 2
Therefore, Li can make 2 more rows of 7 in the array with the remaining value of 14.
