The system of equation that models the problem is as follows;
x + y = 83
1.73x + 1.44y = 130.83
The number of fruit pies sold is 44 and the number of fruit juice sold is 39.
How to solve a system of equation that models a problem?
Mr Sanchez class sold fruit pies for $1.73 each and Mr Kelly's class sold bottles of fruit juice for $1.44 each.
Therefore,
let
x = number of fruit pies sold
y = number of fruit juice sold
Together, the class sold 83 items. Therefore,
x + y = 83
They sold a total of $130.83. Therefore,
1.73x + 1.44y = 130.83
x + y = 83
1.73x + 1.44y = 130.83
1.73x + 1.73x = 143.59
1.73x + 1.44y = 130.83
0.29x = 12.76
x = 12.76 / 0.29
x = 44
Therefore,
y = 83 - 44
y = 39
