The solution
m = s + 5
<span>m - 4 = (3s) - 3 </span>
<span>(s + 5) - 4 = 3s - 3 </span>
<span>s + 1 = 3s - 3 </span>
<span>s = 3s - 4 </span>
<span>-2s = -4 </span>
<span>s = 2 </span>
<span>m = 7 </span>
<span>Check this: </span>
<span>m - 4 = 3s - 3 </span>
<span>7 - 4 = 3(2) - 3 </span>
<span>3 = 6 - 3 </span>
<span>3 = 3 </span>
<span>So Sandy is 2 and Megan is 7.</span>
If the 2nd person pays £52.20, then £52.20 = 3 (from the ratio).
52.20 / 3 = 17.40. 17.40 X 2 (from the ratio) = 34.80.
52.20 + 34.80 = 87.
The meal cost £87.00
