Question

Amber made some cushions to sell at a funfair. She made 25% of the
cushions in the first week. In the second week, she made another 28
cushions. The number of cushions made in the first and second week
was 40% more than the number of cushions that had not yet been made.
She made the rest of the cushions in the third week.
a) How many cushions did Amber make in the third week?
b) How many cushions did Amber make altogether?

Answer 1

Step-by-step explanation:

Basically have to solve 0.25N+28=1.4(N-0.25N-28) to get N which is the total number of cushions and then work back to get the number of cushions in the third week.
