Iwant to make sure i am right i think i no the answer but i want to make sure

Total of 8 cm, 2 cm per year for 4 years result in a total of 2x 4 =8 cm.

The possible number of question are

232,228,224, and 220.

Step-by-step explanation:

Given that Alice correctly solves 35 problems

From the statement, 35 represents between 60 and 65 percent of the whole problem.

Let x be the total number of questions and choose 61% as the percentage Alice solved then,

61% of x = 35

0.61x = 35

x = 35/0.61

= 57.37

Aproximately 57

The possible answer are 58, 57, 56, 55

Since this represent 1 part, the question on test are:

54 * 4 = 232

or

57 * 4 = 228

or

56 * 4 = 224

or

55 * 4 = 220
