The 7 grade student at palm coast muddle school made some apple pies for a bake sale. the school cafeteria also donated 9 pies toward the effort. All the pies at the sale were cut into 8 pieces. if at least 224 pieces of pie were sold in all, how many pies did the students bake

Step-by-step explanation:

Given:

Number of pies donated, Pd = 9

Total pieces of pies sold, Ps = 224 pieces

1 pie = 8 pieces

Ps = pieces of pies donated + pieces of pie baked

224 = (9 * 8) + (Pb * 8)

Pb = (224 - 72) / 8

= 152/8

= at least 19 pies were baked.

The students baked 19 pies.

Step-by-step explanation:

Least total pieces of pies sold = 224

Number of pies donated by school cafeteria = 9

Number of pieces of pies donated by school cafeteria = 9*8 = 72

Number of pieces of pies baked = 224 - 72 = 152

Number of pies baked = 152 : 8 = 192
