On monday, luis picked up seven scones and six large coffees for the office staff. he paid $ 29.97. on tuesday, rachel picked up four scones and five large coffees for the office staff. she paid $ 20.08. what is the cost of one scone? what is the cost of one large coffee?

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
