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.
Answer:
$37.86
Step-by-step explanation:
Multiply 29.99 by 0.0625 to get the sales tax
29.99x0.0625=1.87
Multiply 29.99 by 0.20 to get the tip

Add 1.87 to 29.99
29.99+1.87=31.86
Add 6 to 31.86
31.86+6=37.86
-6-7=-13 because you take -2 and 3 you multiply equals-6 than add -7 and it well give you your answer
