Answer:
Thxx for points how do I enter
Step-by-step explanation:
In the order of operation, multiplying or dividing don't take preference over the other. So with them, you work from left to right.
This means for this question, you first divide, then multiply.
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
