Answer:
Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.
one chocolate cake=?=x
one lemon cake=?=y
$270 spent
need to buy total of 18 cakes
1-chocolate cake =$7
lemon cake = $5
cakes 18=x+y
money $110=$7x+$5y
When i graphed it on the demos calculator i got (10,8).
So 10= the number of chocolate cake brought and 8= the number of lemon cake brought
The number of lemon cakes Jasmine can buy for the party is 8.
System of linear equations
Two equations can be deduced from the question:
a + b = 18 equation 1
$7a + $5b = $110 equation 2
Where:
- a = number of chocolate cakes bought
- b = number of lemon cakes bought
Determining the number of lemon cakes that can be bought
In order to determine the number of lemon cakes that can be bought, take the following steps:
Multiply equation 1 by 7
7a + 7b = 126 equation 3
Subtract equation 2 from equation 3
2b = 16
b = 8
