Answer:
yes
Step-by-step explanation:
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
The sum of -2 and -7 is given as follows :

Now soo we have,
-2 – 7
This gives us: -9
