Sarah sold 66 posters

<em><u>Solution:</u></em>

Let "a" be the number of shirts sold

Let "b" be the number of posters sold

<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>

Therefore,

number of shirts sold + number of posters sold = 178

a + b = 178 ----------- eqn 1

<em><u>She sold 46 more tshirts than poster</u></em>

Number of shirts sold = 46 + number of posters sold

a = 46 + b --------- eqn 2

<em><u>Substitute eqn 2 in eqn 1</u></em>

46 + b + b = 178

2b = 178 - 46

2b = 132

b = 66

Thus she sold 66 posters

Step-by-step explanation:

to be honestly, i don't know how to do this in my head or if there is any formulae to that, every year when interest adds to principal it would makes the principal more and there would be a new amount of interest, but there is a compound interest calculator on internet, i typed the number in and it tells me the answer.

I need help please I need it
SashulF [63]

Step-by-step explanation:

It asks you to choose values for w, the width, and evaluate the equation for each. It describes the constraint "the perimeter of 20 units" The perimeter of a rectangle is the length of all the lines of a regtangle.

Or

2L + 2W = 20 reduce this to simplest for by dividing both sides by 2;

L + W = 10, so the length plus the width is 10. Rearrange it to be W = 10 - L. Values of W can range from 1 to 9. Now sove for a few points in the function.

f(W) = 10W - W^2

3; 10(3) - 3^2 = 30 - 9 = 21.

If we look at the constraint, L = 10 - W, when the width is 3 the length must be 7. The area of a rectangle is L x W, 3 x 7 = 21. That checks against the function.

Solve for additional points.

4; 10(4) - 4^2 = 40 - 16 = 24.

If W is 4 the L is 6 and 4 x 6 = 24

sarah spent a total of 10 on oranges and apples at the supet market. if she spent 3 dollars less for oranges than she did on app
beks73 [17]

Let's write 2 equations from the two statements given.

<em>Sarah spent 10 dollars on both oranges and apples</em>

<em />

Let the price of oranges be "x" and price of apples be "y", thus we can write:

x+y=10

Oranges cost 3 less than apples, thus we can say:

y-3=x

We can substitute this into the first equation and solve for y:

\begin{gathered} x+y=10 \\ y-3+y=10 \\ 2y=10+3 \\ 2y=13 \\ y=\frac{13}{2} \\ y=6.5 \end{gathered}

Thus, let's solve for x now,

\begin{gathered} x=y-3 \\ x=6.5-3 \\ x=3.5 \end{gathered}

We want the price of oranges (x), thus,

<em>Price of Oranges = $3.50</em>
