159.60
Step-by-step explanation:
If Joel gets 20% off, he still has to pay (100-20) or 80%
The cost of the tablet is now 190 * .80
Then he has to pay 5% sales tax.
The tax is the prices times 5% plus the original price
190 *.80 *(1+.05)
or 190 *.80 *(1.05)
Instead of adding the sales tax, he subtracted the sales tax.
The total he needs to pay is
190 *.80 *(1.05)
159.60
Hope this helps :)

The equation says
A=p(1+r)^t
A=103(1+0.02)^t
So the interest rate is
0.02*100=2%
Answer:
Step-by-step explanation:
Is 1.450 correct? 145 would make more sense. I'd even go with 1,450, just for a laugh. I'll assume 1.450 is the correct number here. I'll assume assute the question eventually asks how old are A and B.
A = 49(B)
A+B=1.450
Substitute:
49B+B=1.450
50B = 1.450
B = 0.029
A = 49(B)
A = 49*(0.029)
A = 1.421
