Answer:
$2000 was invested at 5% and $5000 was invested at 8%.
Step-by-step explanation:
Assuming the interest is simple interest.
<u>Simple Interest Formula</u>
I = Prt
where:
- I = interest earned.
- P = principal invested.
- r = interest rate (in decimal form).
- t = time (in years).
Given:
- Total P = $7000
- P₁ = principal invested at 5%
- P₂ = principal invested at 8%
- Total interest = $500
- r₁ = 5% = 0.05
- r₂ = 8% = 0.08
- t = 1 year
Create two equations from the given information:
Rewrite Equation 1 to make P₁ the subject:
Substitute this into Equation 2 and solve for P₂:
Substitute the found value of P₂ into Equation 1 and solve for P₁:
$2000 was invested at 5% and $5000 was invested at 8%.

Answer:
8 hours
Step-by-step explanation:
Joe spends 18.75% of his working day washing cars.
Joe spends 1.5 hours washing car.
Therefore 18.75% is equal to 1.5 hour.
18.75% = 1.5 hour
1% = 1.5 ÷ 18.75 = 0.08 hour
100% = 0.08 x 100 = 8 hours
Answer: 30%
Step-by-step explanation:
Percent error = 
Estimated number of games win this year = 7
Actual number of games won = 10
Now , the percent error of Doug’s estimate = 
Hence, the percent error of Doug’s estimate = 30%
It's suppose to be -18 so I guess no real number....
Answer:
The answer is (4,2)
Step-by-step explanation:
in the point (-4,5) X=-4 AND Y=5
so if you move 8 units right, the X increases by 8(because the the x axis is left and right) so X transform into 4= -4+8=4
With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2
The new coordiantes are(4,2)
