Torri had $20 to buy a birthday present for her dad. She decided to buy a DVD for $18. The sales tax is 7 percent. Does she have
vesna_86 [32]

First, we need to calculate the cost of the sale tax. To do it, we are going to convert the sale tax from percentage to fraction by dividing it by 100, and then we are going to multiply the cost of the DVD by the sale tax:

Sale.Tax=\frac{7}{100}

Now, we can multiply the cost of the DVD by the sale tax to find the cost of the sale tax:

Cost.Sale.Tax=18(\frac{7}{100)} )=9(\frac{7}{50} )=\frac{63}{50} =1.26

Now that we know that the sale tax is $1.26, we are going to add the cost of the sale tax to the cost of the DVD and check if that sum is less or equal than Torri's money (20$):

Total.Cost=18+1.26=19.26

Since $19.26\leq$20, we can conclude that Torri has enough money to buy the DVD. In fact, Torri will end with a change of $0.74 after buying the DVD.

Change<br>2.215(1 and 5 are recurring/repeating decimals)<br>in form of​ a/b
Romashka-Z-Leto [24]

Answer:

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200
