Compute the selling price of a sports drink that has a cost of $1.25 per item. The store needs to generate a profit of $0.50 per

luda_lava [24]

Answer:

The selling price would be $\$1.75$ .

Step-by-step explanation:

We have been given that a sports drink has a cost of $1.25.

We need to figure out the selling price of the sports drink so that the store is able to generate a profit of $0.50 per drink.

We know that profit is found by subtracting the cost of an item from selling price of the item. Therefore, selling price of the item can be found by adding the profit to the cost.

Therefore, the required selling price of the sports drink would be:

$\$1.25+\$0.50=\$1.75$

❖ 6 + 45 ÷ 3² = 11

Follow order of operations:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

(Note: Multiplication and division can be done in either order as well as addition and subtraction.)

There are no parenthesis in this problem so we skip to exponents. The exponent is 3² which is 3 x 3 = 9.

We then have division. 45 ÷ 9 = 5

Our last step is addition.

Add:

6 + 5 = 11

Here is a sales tax of $9 on an item that costs $120 before tax. the sales tax on a second item is $19.05. how much does the sec

Annette [7]

% of sales tax = 9/120 x 100 = 900/120 = 7.5%

Let the cost of the second item be x, then 7.5/100 x = 19.05
0.075x = 19.05
x = 19.05/0.075 = 254.

Therefore, the cost f the second item is $254
