Answer:
The amount which Jada paid after discount and tax is $ 51.64
Step-by-step explanation:
Given as :
The original price of snacks = $ 53
The price of snacks after applying 10% off coupon = 53 - 10% of 53
Or , The price of snacks after applying 10% off coupon = 53 ( )
or, The price of snacks after applying 10% off coupon = 53 × 0.9 = $ 47.7
Now the tax applied on the original amount = 8 % of $ 53
or, the tax applied on the original amount = × 53
or, , the tax applied on the original amount = =$ 4.24
So The total paid amount = $ 47.4 + $ 4.24 = $ 51.64
Hence The amount which Jada paid after discount and tax is $ 51.64 Answer
Check the procedures in the picture attached.
1. Since we are using direct substitution, the only thing we need to do is replace
by 
(the quantity is approaching to) in our quantity to get:
We can conclude that the correct answer is B) -6
2. Again, since we are using direct substitution, th only thing we need to do is replace by 
(the quantity x is approaching to) to get:
We can conclude that the correct answer is D) 31
3. Direct substitution again, so we are going to replace in our quantity by 
to get:
And since cosine of is 0, and any quantity multiplied by zero is zero:
We can conclude that the correct answer is A) 0
4. Here we need to so some algebra first. Notice that if we use direct substitution, the denominator will be zero, and we cannot divide by zero. So lets massage our quantity first:
Now, we can use direct substitution to get:
We can conclude that the correct answer is B) 4
