Answer:
n>-13
Step-by-step explanation:
so you subtract 4 from -9 then since your not multiplying or divinding by a negative you don't flip the sign
3 times 5 times 2.5 = $37.5
3 x 5 =15
15 x 2.5 =37.5
37.5 x 2 = 75 for both of them
I don't know if this is right or not, but that's how I would solve it!
1x1=1
1x2=2
2x3=6
6x4=24
24x5=120
120x6=720
720x7=5040
the answer is 720 and 5040
Given :
A carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.
To Find :
What was her first error.
Solution :
Her first error is to find Unit price of egg in each carton.
To find, unit price we should divide total amount by number of units :
Unit price for carton of 12 eggs, $ (2.39)/12 = $0.199 .
Hence, this is the required solution.
Answer:
The total amount of money Alex spends on 5 DVD = $ 35.
Step-by-step explanation:
Total number of DVD purchased by Alex = 5
The cost of each DVD = $9
So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)
= 5 x ( $ 9) = $ 45
Now , the discount if 1 DVD = $ 2
So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)
= 5 x ($ 2) = $ 10
⇒ The total amount Alex spends
= Total cost of 5 DVD - Discount on 5 DVD
= $ 45 - $ 10 = $ 35
Hence, the total amount of money Alex spends on 5 DVD = $ 35.
