Step-by-step explanation:
Old. new
100%. 45%
x. 42
45x= 4200
x=$93.33
First, find out how much he made in the week total: 24($8.75) = $210
The, find 1.45% of 210: (.0145)(210) = 3.045
*note that 1.45% = .0145*
Round that number to 3.05 and you have your answer
7(3r-1)-(r+5)=-52
21r-7-r-5=-52
21r-r-5-7=-52
20r-12=-52
Add 12 to both sides
20r=-40
Divide by 20
r=-2
