a roofer charges $60 for the first hour of service call and $25 per hour for each additional hour. The roofer also charges a fee

Temka [501]

Answer:

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

Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat

Anarel [89]

Given:

Number of times Jenna feeds her cat = 2

Cat food each time $=\dfrac{3}{4}\text{ can}$

Number of days = 5

Number of cans she bought = 8

To find:

Did Jenna buy enough cat food.

Solution:

Required food for each time $=\dfrac{3}{4}\text{ can}$

Jenna feeds her cat twice a day.

Required food for a day $=2\times \dfrac{3}{4}\text{ can}$

$=\dfrac{3}{2}\text{ can}$

Required food for 5 days $=5\times \dfrac{3}{2}\text{ can}$

$=\dfrac{15}{2}\text{ can}$

$=7.5\text{ can}$

Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.
