Answer:
An apple costs $2 and a banana costs $1.
Step-by-step explanation:
x = cost of 1 apple and y = cost of 1 banana. So:-
2x + y = 5
2x + 3y = 7
Subtract the first equation from the second. We get:-
2y = 2
y = 1
and since 2x + y = 5, 2 x + 1 = 5 and
x = $2.
The toy is 2(x)-20, x is 100, being the toy car. So 2(100)= 200 -20 =180. The cost of the toy is $180
