Answer: the hourly fee for the rototiller is $3

Step-by-step explanation:

Let h represent the hourly fee for renting the rototiller.

The rental company charged an initial fee of $43 with an additional fee per hour. Assuming that they rented the rototiller for x hours. This means that if they rented the rototiller for x hours, the total amount that they would pay is

43 + hx

If they paid $64 after renting the rototiller for 7 hours, the equation that models this problem would be

43 + 7h = 64

7h = 64 - 43 = 21

h = 21/7 = $3

Answer:

$3 per hour, 64 = 7h + 43

Step-by-step explanation:

First, subtract 43 from 64 to find how much the 7 hours on the rototiller actually costed them, which would be 21. Next, divide 21 by 7 to find the hourly fee, which would be 3. If h represented the hourly fee, the equation for this would be 64 = 7h + 43 meaning 64 (the total cost) is equal to 7 times the hourly fee (7 because she rented it for 7 hours) plus 43 (the initial fee).

by selling a mobile set of rupees 4800 Ramesh gains 25% how much will have we gained by selling it at rupees 4080​
Crank

Answer:

240

Step-by-step explanation:

Gain=25%

Gain=selling price - cost price

Gain = ((selling price - cost price )× 100)/ cost price

25c=(4800-c)100

25c=480000-100c

125c=480000

cost price = 3840

second statement

The selling price was 4080

Cost price 3840

therefore

Gain=selling price - cost price

Gain = 4080-3840

=240
