Answer:
1.58
Step-by-step explanation:
So, we know there are 2.1 pounds, and for every pound it costs 0.75 dollars.
We can multiply the 2.1 by the 0.75 to find our answer.
The easiest way to do this is multiply the two numbers on 2.1 seperatly:
2 * 0.75 = 1.5
0.1 * 0.75 = 0.075
Then add them together:
1.5 + 0.075 = 1.575
Now we can round this to the nearest cent(hundreths place), and since the thousandths place is 5, we round up:
1.58
So our answer is $1.58!
Hope this helps!

Answer:
1. $27.30 2. $48.00 3. $15.75 4. $24.20 5. $31.00 6. $40.80
Step-by-step explanation:
1. $13.00 + (1.10)($13.00)
= $ 27.30
2. $60.00 - $60.00(0.20)
= $48.00
3. $15.00 + $15.00(0.05)
= $15.75
4. $22.00 + $22.00(0.10)
= $24.20
5. $25.00(0.06) + $25.00(0.18) + $25.00
= $31.00
6. $32.00(0.075) + $32.00(0.20) + $32.00
= $40.80
Hope this helped :)
