The total number of pancakes at any given time...
T(t)=P(t)+S(t)
T(t)=12t+255t
T(t)=267t
Answer:
$408
Step-by-step explanation:
What we know:
John earns a 3% commission for every car he sells.
He sold a car today for $13,600.
Multiply 3/100 by 13,600 to get your answer.
3/100 * 13600
40800/100
$408 in commission
Solution,
y = -x-4......(i)
3x + y =- 16.......(ii)
Now,
Substituting the value of y in equation (ii)
or, 3x + (-x-4)= -16
or,3x - x - 4 = -16
or, 2x= -16 +4
or, x = -12/2
: x = -6
Then,
Substituting the value of x in (i) equation;
or,y= -(-6) - 4
or,y= 6 - 4
: y =2
