A 600
B 900
C 400
D 1,000
The number of stuffed bears the store ordered can be found by multiplying the number of crates (26) by the number of bears in each crate (21):
26 crates * 21 bears/crate = 546 bears
The closest answer choice to 546 is D, 1,000 bears. However, since this is an estimate, we can round the number to the nearest hundred. In this case, the best estimate would be B, 900 bears.
Amy is making jewelry. She buys four different types of beads. The chart below shows how many bags she buys of each type of bead along with how many beads come in each bag.
Type of Bead Number of Bags Number of Beads in Each Bag
star 4 21
square 7 14
circle 9 16
heart 2 43
Estimate the total number of each type of bead Amy buys. Which two types of beads will she have about the same amount of?

To estimate the total number of each type of bead Amy buys, we multiply the number of bags by the number of beads in each bag for each type:
Star beads: 4 bags * 21 beads/bag = 84 beads
Square beads: 7 bags * 14 beads/bag = 98 beads
Circle beads: 9 bags * 16 beads/bag = 144 beads
Heart beads: 2 bags * 43 beads/bag = 86 beads
From the calculations, Amy will have about the same amount of square and circle beads since they both have approximately 98 beads. The correct response is:
Square and circle.

7×198=(7×200)+(7×2)
7 × 198 = 7 × 200 + 7 × 2
7×198=(7×200)−(7×2)
7 × 198 = 7 × 200 - 7 × 2
7×198=(7+100)×(7+90)×(7+8)
7 × 198 = 7 + 100 × 7 + 90 × 7 + 8
7×198=(7×100)×(7×90)×(7×8)
7 × 198 = 7 × 100 × 7 × 90 × 7 × 8
7×198=(7×100)+(7×90)+(7×8)
The correct ways to find 7×198 are:
7×198=(7×200)+(7×2)
7 × 198 = 7 × 200 + 7 × 2
7×198=(7×100)+(7×90)+(7×8)
Therefore, the correct responses are:
- 7×198=(7×200)+(7×2)
- 7 × 198 = 7 × 200 + 7 × 2
- 7×198=(7×100)+(7×90)+(7×8)
To find the best estimate of how many stuffed bears the store ordered, we need to multiply the number of crates by the number of stuffed bears in each crate.
Number of crates: 26
Stuffed bears per crate: 21
Total number of stuffed bears = 26 * 21
Calculating, we get:
Total number of stuffed bears = 546
The best estimate of how many stuffed bears the store ordered is 546.
Therefore, the correct answer is not listed among the options given.
To find out the best estimate of how many stuffed bears the store ordered, we need to multiply the number of crates by the number of bears in each crate.
In this case, the toy store ordered 26 crates of stuffed bears, with 21 bears in each crate.
To find the best estimate, we multiply 26 (the number of crates) by 21 (the number of bears in each crate):
26 * 21 = 546
The best estimate of how many stuffed bears the store ordered is 546.
Given the answer options provided:
A. 600: This is greater than 546, and therefore not the best estimate.
B. 900: This is even greater than 600, and not the best estimate either.
C. 400: This is much smaller than 546 and also not the best estimate.
D. 1,000: This is greater than 900, and definitely not the best estimate.
Therefore, the best estimate of how many stuffed bears the store ordered is 546.
So, the correct answer is none of the options provided.
