Answer:
Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Step-by-step explanation:
When we round 6.2 lb to the nearest pound we round down, because the digit after point is less than 5 (2<5), so
When we round $2.85 to the nearest dollar we round up, because the digit after point is greater than 5 (8>5), so
Now, 6.2 lb of blueberries will approximately cost
Hence, Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
Answer:
<em> 4 pairs of earrings </em>
Step-by-step explanation:
3.75 e + 9.50 < 25
3.75 e < 25 - 9.50 = 15.50
e < 15.50 ÷ 3.75 ≈ 4.13
e =<em> 4 pairs of earrings</em>

4t - 18
The number of folders and notebooks in the equation is given by 3 and 5 respectively.
<h3>How to find number of folders and notebooks?</h3>
let
- x = number of folders
- y = number of notebooks
The equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5
Recall
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3
