Question

Nikki sells some cakes at the school fete. The cake costs $5.80 to make. Nikki wants to make a profit of 80%. How much must she sell the cakes for?​

Answer 1

cp =5.80 $

profit% required = 80%

sp = (100+profit%/100)×cp

= (100+80/100) × 5.80

= (180/100) ×5.80

= 18/5 × 2.9

= 52.2/5 =10.44

therefore , she required to sell her cakes on 10.44 $

to gain profit of 80 %
