Ky wants to buy three shirts, which were originally priced at $49.96 each. How much will the three shirts cost before tax?

Answers

Final answer:

To find the total cost of three shirts priced at $49.96 each before tax, multiply the price of one shirt by three, resulting in a total of $149.88.

Explanation:

The question concerns the calculation of the total cost of three shirts before tax in Mathematics.

To answer it, we simply need to multiply the original price of one shirt by the quantity desired.

Since one shirt is priced at $49.96, the cost for three shirts can be found by performing the following multiplication:

$49.96 × 3 = $149.88

Therefore, the total cost of three shirts before tax is $149.88. This calculation is a straightforward example of applying basic multiplication skills to find the total cost of multiple items.

Thus, for the given value of originally priced at $49.96, the cost  before tax is found to be $149.88.

Add 3b to both sides

Regroup terms

[tex]ac-c=3b-4 [/tex]

Factor out the common term c

[tex]c(a-1)=3b-4 [/tex]

Divide both sides by a-1

[tex]c= \dfrac{3b-4}{a-1} [/tex]

Tony has 7/8 of a candy bar. he wants to split the bar into servings that are 3/10 of the bar. how many servings can he make?

Answers

alright, so let's make both 7/8 and 3/10 into fractions with the same denominator.
The lowest common denominator for both of these is 80.
So, we multiply the top and bottom of 7/8 by 10, and the top and bottom of 3/10 by 8 to get fractions we can compare.
So, we have 70/80 of a candy bar, and we want to make servings of 24/80 each.
How many times can 24 go into 70? 2 times, with a remainder of 22.
So, Tony can make 2 servings.

The equation y = 1725 - 75x represents the amount of money y (in dollars) left in your lunch account after x weeks. 20 weeks go by. FInd the domain and range of the function.

Answers

y= -75x +1725
y= -75(20) +1725
y = -1500 + 1725
y= 225 = range
225= -75x +1725
225 - 1725= -75x
-1500=-75x
-1500/-75 = -75x/-75
x = 20 = domain
Final answer:

The domain of the function y = 1725 - 75x, representing money left in a lunch account, is between 0 and 20 weeks. The range is the amount of money, from $225 to $1725.

Explanation:

The equation y = 1725 - 75x represents the amount of money left in a lunch account after x weeks. If we consider the function f(x) for 0 ≤ x ≤ 20. The domain of this function, which is the set of allowable values for x, is from 0 to 20, inclusive. This means that x can take on any real number value between 0 and 20. For the range, we calculate the minimum and maximum values of y using the equation, which are y when x = 0 and y when x = 20 respectively. For x = 0, y = 1725 and for x = 20, y = 1725 - 75(20) = 1725 - 1500 = 225. So the range of y is from 225 to 1725 dollars.
