The value of C based on the information given about the integer is C. 22.

<h3>How to calculate the value?</h3>

From the information given,

b² + bc - 23 = 0

Let the assumed value for a = 1

b² + bc - 23 = 0

1² + (1 × c) - 23 = 0

1 + c - 23 = 0

c = 23 - 1

c = 22.

Last year at a certain high school, there were 96 boys on the honor roll and 60 girls on the honor roll. This year, the number o
djverab [1.8K]

Answer:

19%

Step-by-step explanation:

Last year:

Number of boys on honor roll = 96

Number of girls on honor roll = 60

Total students on honor roll = Number of boys on honor roll + Number of girls on honor roll

= 96 + 60

= 156

This year:

The number of boys on the honor roll increased by 25%

Number of boys on honor roll = 25% of 96 + 96

= 0.25×96 + 96

= 24 + 96

= 120

The number of girls on the honor roll increased by 10%.

Number of girls on honor roll = 10% of 60 + 60

= 0.10 × 60 + 60

= 6 + 60

= 66

Total students on honor roll = Number of boys on honor roll + Number of girls on honor roll

= 120 + 66

= 186

Percentage the total number of students on the honor roll increase = (186 - 156) / 156 × 100

= 30 / 156 × 100

= 0.19 × 100

= 19% to the nearest tenth
