Complementary means they add to 90°
f=90-g
f=4g
4g =90-g
5g=90
g=18
f=4g=4(18)=72
Answer: f=72°, g=18°

let the price of a slice of pizza be 'p' and that of soft drink be 's'
6 p + 5 s = 31.60............equation (i)
5 p + 4 s = 26.02............equation (ii)
6 p + 5 s = 31.60............×4
5 p + 4 s = 26.02............×5
24 p + 20 s = 126.4
25 p + 20 s = 130.1
p = 3.7
Answer = 3.7 Dollars
