What are Arithmetic operations?
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators
Given data as :
Cost for six muffins = $7.74
Cost for eight juice boxes = $5.52
Since cost for six muffins = $7.74
So, cost for one muffin = 7.74/6
Cost for one muffin = $1.29
And cost for seven muffin = 7 × 1.29
Cost for seven muffin = $9.03
Since cost for eight juice boxes = $5.52
So, cost for one juice box = 5.52/8
Cost for one juice box = $0.69
And cost for 14 juice box = 14 × 0.69
cost for 14 juice box = $9.66
Total cost for 7 muffins and 14 juice boxes = $9.03 + $9.66
Total cost for 7 muffins and 14 juice boxes = $18.69
Hence, $18.69 would cost for 7 muffins and 14 juice boxes.
