Answer:
y = 1/2x - 7/2
Step-by-step explanation:
y = 1/2x + b
-3 = 1/2(1) + b
-3 = 1/2 + b
-7/2 = b

We will find the rate of Greg and Josh earning money that is
the amount of money they receive per unit time (hour)
Since the trip is in 3 weeks,
Number of hours Josh worked = 3 weeks * (5 hours/week) = 15
hours
Number of hours Greg worked = 3 weeks * (8 hours/week) = 24
hours
Josh’s rate = $480/15 hrs = $32/hr
Greg’s rate = $480/24 hrs = $20/hr
Therefore
Josh makes $12/hr more than Greg
Answer:
$607.75
Step-by-step explanation:
As a first approximation, compound interest will be slightly higher than simple interest for a relatively short time period. Here simple interest at 5% for 4 years will add 4×5% = 20% to the value, adding about $100 to the initial $500 value. That is, we expect the value in 4 years to be slightly more than $600.
The appropriate answer choice is $607.75.
_____
The actual amount can be calculated using the multiplier 1.05 for each of the 4 years, or 1.05^4 ≈ 1.21550625 for the entire period. Then the predicted item value is ...
$500 × 1.21550625 = $607.753125 ≈ $607.75
I'm not sure if you meant the tax was on the original proce or not, so here's both answers:
Tax on original price: $3010
Tax after sale: $2968
To get the amount off from the sale
3500x.2=700
3500-700=2800
To get the tax
(Tax on original price) 3500x.06=210
(Tax after sale) 2800x.06=168
Add tax onto price
(Tax on original price) 2800+210=3010
(Tax after sale) 2800+168=2968
