Answer:

80 gummy bears are in 4 servings.

Step-by-step explanation:

2 servings=40 gummy bears

3 servings=60 gummy bears

Add 20 gummy bears for every serving.

5 servings=100 gummy bears

100-20=<u>80 gummy bears are in 4 servings</u>

OR you can also do:

40÷2=20 gummy bears are in each serving

So, 4x20=<u>80 gummy bears are in 4 servings</u>

Sarah needs 10 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabri

Aleks [24]

<h2>Hello!</h2>

The answer is:

The fabric will cost $4.58

D.$4.58

Since it's a conversion exercise, we need to pay special attention to the conversion procedure.

From the statement we know that:

$1ft=0.305m$

So, if she needs 10 feet of fabric, we need to convert it to meters, and then, calculate its cost.

We have that:

$10*1ft=10*0.305m\\\\10ft=3.05m$

Now, we have that each meter of fabric cost $1.50, so, 3.05m of fabric will cost:

$\frac{1m}{1.50(dollars)}=\frac{3.05m}{cost}\\\\cost=\frac{3.05m*1.50(dollars)}{1m}=4.575(dollars)=4.58(dollars)$

Hence, we have that the cost of the fabric will be $4.58.

The correct option is: D.$4.58

Have a nice day!

The price of a pair of jeans at a store increased by 25% to $40. Find the price of the pair of jeans before the increase.

VARVARA [1.3K]

We can display this as an algebraic equation:

x * 1.25 = 40

Now divide by 1.25

x = 40/1.25
x = 32

Hope this helps!
