<em>x</em> = liters of 40% solution, which contributes a total of 0.4<em>x</em> liters of acid
<em>y</em> = liters of 30% solution, which contributes a total of 0.3<em>y</em> liters of acid
The chemist wants to end up with 50 liters, so
<em>x</em> + <em>y</em> = 50
and 36% of this -- 0.36 (50 liters) = 18 liters -- is acid, so that
0.4<em>x</em> + 0.3<em>y</em> = 18
Solve for <em>x</em> and <em>y</em> :
<em>y</em> = 50 - <em>x</em>
0.4<em>x</em> + 0.3 (50 - <em>x</em>) = 18
0.4<em>x</em> + 15 - 0.3<em>x</em> = 18
0.1<em>x</em> = 3
<em>x</em> = 30
<em>y</em> = 20
Answer:
Initial cost for Company G: $27
Initial cost for Company H: $25
Explanation:
✅Company G: c = 27 + 10h
The equation for Company G is given in slope-intercept form, c = mh + b
Where,
m = unit rate/hourly fee
b = y-intercept/starting value/initial cost
Thus:
Initial cost for Company G = $27
✅Company H: the initial cost for company H would be y-intercept of the table of values given.
The y-intercept = the cost at when the number of hours is 0.
From the table, when number of hours is 0, cost = $25.
Therefore, the initial cost for Company H = $25
