A Walgreens purchase comes to $28. Find the total cost if a 2% sales tax is included.
OverLord2011 [107]

Answer:

The answer is $28.56

Step-by-step explanation:

To find the 2% sales tax, you need to multiply the 2% or 0.02 by 28.

Doing this will give you 0.56.

Then you add 0.56 to 28 to get 28.56, hence, $28.56 is the total cost.

Hope it helps!

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit
Mademuasel [1]

<u>Answer:</u>

y = -\frac{2}{3}x + 490

gradient = = -\frac{2}{3}

y-intercept = 490

<u>Step-by-step explanation:</u>

• The slope-intercept form of an equation takes the general form:

\boxed{y = mx + c},

where:

m = slope,

c = y-intercept.

• We are given the equation:

2x + 3y = 1470

To change this into the slope-intercept form, we must make y the subject:

3y = -2x + 1470          [subtract 2x from both sides]

⇒ y = -\frac{2}{3}x + \frac{1479}{3}        [divide both sides by 3]

⇒ y = -\frac{2}{3}x + 490

• Comparing this equation with the general form equation, we see that:

m = -\frac{2}{3}

c = 490.

This means that the gradient is \bf -\frac{2}{3}, and the y-intercept is \bf 490.

I have trouble understanding word problems. May I please have help with number 15? Thank you very much!

Basically you do fractions side by side. so, 6/3=15/h and then cross multiply to get your answer so that would give you 3h=80, then divide 80÷3

Solve for x. x2 + x - 6 = 0 A. -2, -3 B. -2, 3 C. 2, -3 D. 2, 3
stiv31 [10]

Factor x^2 + x - 6

(x - 2)(x + 3) = 0

Solve for x

Ask yourself; When will (x - 2)(x + 3) equal zero?

When x - 2 = 0 or x + 3 = 0

Then solve for each of the two equations above

<em>x = 2, -3</em>

<u>Answer: C. 2, -3</u>
