Answer:
x= 5 ........................ .......
Answer:
Store 1= $150
Store 2= $250
Step-by-step explanation:
Let the amount invested by store 1 be x while store 2 be y hence
10x-8y=1300 Eqn 1
Make x the subject of the formula for the first equation
10x=1300+8y divide both sides by 10
X=130+0.8y
6x+5y=2250 Eqn 2
Substituting where there’s x with 130+0.8y in equation 2 we obtain
6(130+0.8y)+5y=2250
780+4.8y+5y=2250
9.8y+780=2250
9.28y=2250-780=1470
Y=1470/9.8=150
X=130+0.8y= 130+0.8(150)=250
You can solve a system using substitution, elimination, or graphing method.
If you solve using substitution or elimination, the variable will cancel out on both sides and you will be left with a number equal to a number. If "number = number" is a TRUE statement, then the solution is ALL Real Numbers. <em>If it is a FALSE statement, then you will have NO solutions.</em>
If you solve using the graphing method and the lines are exactly the same, then the solution is Infinite solutions (aka ALL Real Numbers). <em>If the lines are parallel, then you will have NO solution.</em>
Answer:
1)- Variable utilities cost per machine hour = 1.6 per machine hour
2)- Fixed cost = 1740
3)-Total cost on 1220 Machine hour will be
= 3692
Step-by-step explanation:
1) CALCULATE VARIABLE UTILITIES COST PER MACHINE HOUR :
Variable utilities cost per machine hour = Change in cost/high machine hour-low machine hour
=4076-3388/1460-1030
Variable utilities cost per machine hour = 1.6 per machine hour
2) Fixed cost = Total cost-variable cost
= 3388-(1030*1.6)
Fixed cost = 1740
3) Total cost on 1220 Machine hour will be (1220*1.6+1740) = 3692
