The math club has 12 members. Each member pays monthly dues of $13.20. On the first day of the month, 8 members paid their dues. The remaining members paid their dues on the second day of the month. How much money was collected in dues on the second day of the month?

$52.80

Step-by-step explanation:

Number of members = 12

Monthly due per member = $13.20

Total amount expected = $13.20 × 12 = $158.40

On the first day of the month, 8 members paid their dues. Total amount paid will be:

= 8 × $13.20

= $105.60

The money that was collected in dues on the second day of the month will be:

= $158.40 - $105.60

= $52.80

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

your answer would be 10x - 1
