Answer:
$9
Step-by-step explanation:
The breakfast before tip costs x.
The tip is 20% of x.
The tip is $1.80.
20% × x = 1.80
0.2x = 1.8
x = 1.8/0.2
x = 9

If x is the age and y is the diameter of the trunk, write the equation:
ax+b=y
We must solve for a and b with the given information.
If (x, y) is (1, 4), we have:
a+b=4
If (x, y) is (10, 25), we have:
10a+b=25
Multiply the first equation by 10 to get:
10a+10b=40
Subtract the second equation from this to get:
9b=25
Thus b=25/9. a=4-25/9=11/9, so our equation is 11x/9+25/9=y.
