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
The answers to the questions
Hi, thank you for posting your question here at Brainly.
Jin: 3 small candles and 1 medium candle
3s + 1m = 3.85 <-- equation 1
Trish: 4 small candles and 5 medium candles
4s + 5m = 10.45 <-- equation 2
Solving the system of equations,
s = $0.8/small candle
m = $1.45/medium candle
