I believe this is the answer, im so sorry if im wrong
8 dollars is discount
100-20=80 so
8 dollars =80%
1 dollar=20%
80+20=100
8 + 1 = 9
original price=$9
Divide total price by quantity:
15.60 / 6 = 2.60
Unit price = $2.60
1) £20
2) 18/4 * 7 = 31,5msquared
3) X= (3-1)/5 = 2/5 = 0.4
4) A(n) = 2 + 5n
5) t(3) = 6*3 + 2 = 20
Add 5 to 5, or multiple 5 by 2.
