After using the arithmetic: They sold 40 small bowl of ice cream and 23 large bowl of ice cream.

Arithmetic is an elementary a part of arithmetic that consists of the study of the properties of the standard operations on numbers—addition, subtraction, multiplication, division, operation, and extraction of roots.

Main body:

Cost of small bowl of ice cream = $2.25

Cost of large bowl of ice cream  = $3

Total number of bowls sold = 63

total value  = $159

let number of small bowls be x and  large bowl be y.

Hence ,

x +y = 63                       —(1)

2.25 x +3 y = 159          —(2)

from equation 1 substitute the value of x in equation 2 .

2.25 x + 3 (63- x) = 159

2.25 x + 189 – 3x = 159

taking like terms to one side ,

3x – 2.25x = 189-159

0.75x = 30

x = 40

so x = 40 then y = 23.

Hence they sold 40 small bowl of ice cream and 23 large bowl of ice cream.
