Answer:
$1.25 to park a car and $3.50 to park a truck
Step-by-step explanation:
Set up a system where c is the number of cars parked and t is the number of trucks:
3c + 2t = 10.75
7c + t = 12.25
Solve by elimination by multiplying the bottom equation by -2 to eliminate t:
3c + 2t = 10.75
-14c - 2t = -24.5
Add them together and solve for c:
-11c = -13.75
c = 1.25
Then, plug in 1.25 as c in the equation to solve for t:
3c + 2t = 10.75
3(1.25) + 2t = 10.75
3.75 + 2t = 10.75
2t = 7
t = 3.5
So, it costs $1.25 to park a car and it costs $3.50 to park a truck
Answer:
The first one lol
Step-by-step explanation:
For this question, set up an equation. 60 times what decimal is 27?
60x=60
x=0.45
Convert this decimal to a percentage by multiplying it by 100:
45%
For this question, set up an equation. 55% (or 0.55) times what number equals 22?
0.55x=22
<em>*Divide both sides by 0.55*</em>
x=40
Hope this helps!!
