PART A
s = <span>the number of packets of strawberry wafers ;
c = </span><span>the number of packets of chocolate wafers ;
3 </span>× s + 1 × <span>c = 30 ;
s + c = 22 ;
PART B
</span>The method of solving "by substitution"<span> works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
</span>
c = 30 - 3s;
s + ( 30 - 3s ) = 22;
30 - 2s = 22;
30 - 22 = 2s;
8 = 2s;
s = 4 ;
c = 30 - 12 ;
c = 18 ;
Your answer would be 9 hours
Answer:
The cost of parking the car for 1 hour = $2.5
Step-by-step explanation:
Cost of parking car for two hours = $5
Now, let the cost of parking the car for one hour be $x
Since, the car is parked for two hours and the cost charged is $5
So, each hour the cost of parking is same ⇒ Cost of parking one hour is half the cost of parking the car for two hours.
Since, the cost of parking the car for one hour = $x
So, cost of parking the car for two hours = 2x
But this cost is given to be $5
⇒ 2x = 5
⇒ x = 2.5
Hence, The cost of parking the car for 1 hour = $2.5
