3. The original price of the trampoline is $72
The marked off price is 72 times 70 percent.
72 x .70 = 50.4
The sales tax is 5%
50.4 + 50.4 x 0.05
50.4 + 2.52
52.92
He paid $52.92 in total.
4. A store bought a leaf blower for $48.50 and marked it up 100%
This cost would be 48.5 x 2 which is $97
The sales tax is 6%
97 + 97 x 0.06
97 + 5.82
102.82
The total cost was $102.82
Answer: 1,200 ml
Step-by-step explanation:
The ratio is 1 : 5.
If 200 ml of concentrate is used, the water used will be:
1 : 5
200 : x
x = 1,000 ml of water
The amount of juice would be:
= water + concentrate
= 1,000 + 200
= 1,200 ml
Answer: B.

Step-by-step explanation:
Let's solve your system by elimination.
4x−2y=8;−2x+2y=6
Add these equations to eliminate y:
4x-2y=8
-2x+2y=6
2x=14
Substitute 7 for x in 4x−2y=8:
(4)(7)−2y=8
−2y+28=8 (Simplify both sides of the equation)
−2y+28+−28=8+−28 (Add -28 to both sides)
−2y=−20
−2y/−2=−20/−2 (Divide both sides by -2)
y=10
Answer:
