Ms. Peo decides to bring in doughnuts for coworkers and students. She buys two for each student and sixty for the staff. The total number of doughnuts can be modeled using the function rule f(x) = 2x + 60, where x is the number of students in her class.

sorry not knowing about that

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
