Mohal decides to estimate the volume of a coffee cup by moldering it as a right cylinder mohal measures its radius as 2.9 cm and it’s volume as 214 cubic centimeters find the height of the cup in centimeters round your answer to the nearest tenth if necessary

11 large mowers were sold.

Step-by-step explanation:

Let x represent the number of small mowers sold.

Let y represent the number of large mowers sold.

The total number of mowers sold was 30. This means that

x + y = 30

The small mower costs $249.99. The large mower costs $329.99. Total sales of mowers for the year were $8379.79. This means that

249.99x + 329.99y = 8379.79 - - - -1

Substituting x = 30 - y into equation 1, it becomes

249.99(30 - y) + 329.99y = 8379.79

7499.7 - 249.99y + 329.99y = 8379.79

- 249.99y + 329.99y = 8379.79 - 7499.7

80y = 880.09

y = 880.09/80

y = 11

x = 30 - y = 30 - 11

x = 19
