Answer:
(A) 33.9 (B) 22.6
Step-by-step explanation:
We first need to round to the nearest dollar for both prices. Lets examine both numbers.
$30.<u>1</u>2 $19.<u>9</u>3
We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.
Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now

Now we can find the final price for each number by adding the tax to the rounded price.

Hence, (A) 33.9, (B) 22.6
Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905
Annual profit=75,000÷6=12,500
ROI=12,500÷15,000=0.8333×100
=83.33%
He will spend at least $27. He has already spent $16
27-16=11
So, Henry will spend at least 11 more dollars
C ≥ 11
