Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. she paid a total of $4.25 for these items, before tax. exactly how many erasers did stefanie buy?

Stefanie bought 10 erasers

Step-by-step explanation:

We can establish the following equation:

TP = NP*PP + NE*EP

Where:

TP = Total price; (4.25)

NP = Number of pencil packages; (1)

PP = Pencil Package's Price; (1.75)

NE = Number of erasers; (What we are looking for)

EP = Erasers Price; (0.25);

Then:

4.25 = 1*1.75 + NE*0.25;

4.25 - 1.75 = NE*0.25;

2.5/0.25 = NE;

10 = NE.

the answer is simply just 6n add the two together as they have an n
