Answer:
l = 23 cm and w = 5.7 cm
Step-by-step explanation:
Perimeter = twice the length plus twice the width
let w = width
let l = length
l = 5.9 + 3w
57.4 = 2(5.9 + 3w) + 2w
57.4 = 11.8 + 6w + 2w
57.4 = 11.8 + 8w
45.6 = 8w
w = 5.7
Substitute 5.7 for 'w' to get 'l':
l = 5.9 + 3(5.7)
l = 23
If charlie gets £108, then alice gets £81
First: Figure out the cost per candy bar currently by dividing 3.22 and 14
3.22 / 14 = 0.23
Second: Add in 0.15 to your total to solve for the prior cost of the candy
0.23+0.15 = $0.38
