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

Answer:
6/24=x/100
Step-by-step explanation:
Computation for the equation that could be used to find x, the percent of lemonade in the whole recipe
The EQUATION to find x, the percent of lemonade in the whole recipe will be :
6 /24=x/100
Hence, cross multiply
x=6/24×100
x=0.25×100
x=25%
Therefore the equation to find x, the percent of lemonade in the whole recipe will be 6/24=x/100 which will give us x= 25% when will cross multiply.
