Answer:
<h2>y=60+25h+0.3r</h2>
Step-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
9 x 6 = 54
54 - 4 = 50
50 + 5 = 55
i think, your question isn't very clear
Divide all of the ingredient amounts by 3 so that way it will be for two
