Deshawn’s gross income was $368.20. His net income was $289.03. What was the total amount of his deductions? Responses A. $657.2
Mnenie [13.5K]
So gross income is the total income that Deshawn receives, while net income is the income he has after deductions.
So to find the deductions, we simply subtract the gross from the net income:
368.20 - 289.03 = 79.17

A mass club has 40 members the number of girls is five less than two times the number of boys how many members are boys how many
Lorico [155]

Answer:

15 boys and 25 girls

Step-by-step explanation:

The sum of boys (b) and girls (g) is given as 40:

g + b = 40

The number of girls is 2 times the number of boys minus 5:

2b - 5 = g

First formula can be rewritten as g = 40 - b

Then you can substitute this for g in the second, and you get:

2b-5 = 40-b

Which simplifies to:

2b + b = 40 + 5

3b = 45

b = 15

g = 40-15 = 25

15 boys, 25 girls.
