Question

Jessie baked p cupcakes on Saturday. She baked (p + 3) more cupcakes on Sunday than on Saturday. She baked 30 cupcakes altogether. How many cupcakes did Jessie bake on Saturday?​

Answer 1

9 cupcakes on Saturday

Explanation:

(p + 3) more than p is p + p + 3 = 2p + 3

on Saturday she baked p

on Sunday she baked 2p + 3 , then

p + 2p + 3 = 30

3p + 3 = 30 ( subtract 3 from both sides )

3p = 27 ( divide both sides by 3 )

p = 9

She baked 9 on Saturday and 21 on Sunday
