Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25.
If Mark's total cost is $156.25, which of the following equations can be used to find how much each notebook cost? Select two that apply.
Something like one of these????
25(1.25) + 25(n) = 156.25 ?
25n = 156.25 - 25 (1.25) ?
25n = 125 ?
n = ( 156.25 - 25(1.25) ) / 25 ?
