Ronnie’s Rentals charges $25 plus $15 per to rent a chain saw for 5 hours. Write an expression to show how you could calculate t

iragen [17]

Answer:

The expression of total amount David paid is

y=25+ 15x

where y represents total amount in dollar, x is time in hour.

The total amount that David paid is $100.

Step-by-step explanation:

Given that,

Ronnie's Rentals charges $25 plus $15 per hour to rent a chain for 5 years.

Let

Ronnie's rents a chain for x hours.

Given that,

Rental charge of a chain for 1 hour is $15

Rental charge of a chain for 2 hour is $(15+15) = $30 = $(2×15)

Rental charge of a chain for 3 hour is $(15+15+15) = $45 = $(3×15)

From the above we conclude that,

∴Rental charge = Time ×$15

Rental charge of a chain for x hour is = $(x.15)=$15x

The expression of total amount David paid is

y=25+ 15x

where y represents total amount in dollar, x is time in hour.

Now plugging x= 5 in the above expression

y= 25 + (15×5)

=$100

The total amount that David paid is $100.

Divide 3 from numerator and denomoinator.

3/3 = 1

15/3 = 5

1/5 is the simplified form.

A blueberry plant produces about 26 blueberries per day. If the farmer picked 472 blueberries, how many days did the plants prod

Arte-miy333 [17]

Answer:

About 18 days.

Step-by-step explanation:

The problem states that a blueberry plant produces about 26 blueberries per day. So, our answer will be somewhat of an estimate for the amount of days the plants produced blueberries based on the number picked. In order to solve for the number of days, we can set up equivalent ratios (fractions):

$\frac{blueberries}{day}=\frac{26}{1}=\frac{472}{d}$ where 'd' = number of days.

We can cross-multiply and divide in order to find the amount of days:

$\frac{26d}{26}=\frac{472}{26}$

So, d ≈ 18 days.
