Answer:
$125
Step-by-step explanation:
if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price
let a = original price
this equation can be used to represent the question
a x 0.8 = 100 ]]divide both sides by 0.8
a = 100 / 0.8 = 125
Yes because PROPORTIONAL means the lines start on the axis which is the zero and it also has to be in a even line so yes it is proportional
Answer:
$413.83
Step-by-step explanation:
Your earnings for the two weeks are
7.25(40)(2) = 580
The deductions for FICA will be
0.0765(580) = 44.37
The deductions for federal withholding will be
0.14(580) = 81.2
The deductions for state withholding will be
0.07(580) = 40.6
This makes your realized income
580-(44.37+81.2+40.6) = 580-166.17 = 413.83
Answer:
730, 735, 740
Step-by-step explanation:
Let the three consecutive multiples of 5 be, x, x+5 and x+10
Given,
x + x+5 + x+10 = 2205
3x + 15 = 2205
Subtract 15 from both sides,
3x = 2205 - 15
3x = 2190
Divide both sides by 3,
x = 2190/3 = 730
So, x= 730
x+5 = 735
x+10 = 740
