Answer:
1 day = 221 hot coffee cups and 117 iced coffee cups
2 day = 247 hot coffee cups and 234 iced coffee cups
Step-by-step explanation:
A new coffee shop sold 468 cups of hot coffee and 351 cups of iced
coffee during its first two days. The ratio of cups of hot coffee sold to cups of
iced coffee sold on the first day was 17 : 9. On the second day, the shop sold
twice as many cups of iced coffee as the first day. The ratio of cups of hot
coffee sold to cups of iced coffee sold on the second day was 19 : 18.
a) How many cups of each type of coffee did the shop sell the first day?
Let cups of hot coffee be denoted by x
Then
17x+ 19x= 468
or
36x= 468
x= 13
On the first day the number of hot coffee cups sold are 17y or 17*13= 221 cups.
On the second day the number of hot coffee cups sold are 19y or 13*19= 247 cups.
Similarly Let cups of iced coffee be denoted by y
Then
9y+18y= 351
27y= 351
y= 351/27= 13
On the first day the number of iced coffee cups sold are 9y or 13*9= 117 cups.
On the second day the number of iced coffee cups sold are 18y or 13*18= 234 cups.
