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:
v=18
Step-by-step explanation:
26=8+v
<em>Swap sides:</em>
8+v=26
<em>Subtract 8 from both sides:</em>
8+v-8=26-8
<em>Group like terms:</em>
v+8-8=26-8
<em>Simplify the arithmetic:</em>
v=26-8
v=18
