each scone cost 2.67

each coffe cost 1.88

Step-by-step explanation:

Luis:

(1)  29,97=7Scons+6Coffe

(2)  Scons=(29,97-6coffe)/7

Rachel

(3)  20,08=4scons+5Coffe

if we replace eq.(2) in (3)

(4)   20,08=4*(29,97-6coffe)/7+5coffe

 (5)  20,08=17.1257+1,5714 coffee

(6)  coffe=1,88

if we replace (6) in (2) we obtain

scons=(29,97-6*1.88)/7=2.67
