The cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.
<h3>Equation</h3>
Plan A:
Manufacturer's recommended list price = 90%
= 90% × 30
= 0.9 × 30
= $27
Total cost of plan A = $30 + $27
= $57
Plan B:
Manufacturer's recommended list price = 70%
= 70% × 90
= 0.7 × 90
= $63
Total cost of plan B = $90 + $63
= $153
Therefore, the cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.

Answer:
80% of the students passed the algebra test
Step-by-step explanation:
So for this question, they want to know the percentage of the people that passed.
20 out of 25 students passed, we could find the percentage using two ways:
-------
1. We can use proportions to figure out the percentage (This can only work if the numbers are factorable by 100 such as 10, 25, 50...)
25 × 4 would equal 100. You must multiply the same number to the top as well.
So 20 × 4 = 80
--------
2. We can divide the two numbers
20 ÷ 25 = 0.8
When changed into a percentage, 0.8 would be 80%
-------

Answer:
<u>(7.5-2.1) /2</u>
<u>If the shortest side measures 2.1 m</u>.
<em>7.5-2.1 =5.4.</em> Then divide by 2 each side is 2.7m
Step-by-step explanation:
6b < 42 or 4b + 12 > 8
6b < 42
= 6b/6 < 42/6
= b < 7
4b + 12 > 8
=4b - 12 + 12 < -12+8
= 4b > - 12 + 8
= 4b > -4
= 4b/4 = -4/4
b > -1
so
7 > b > -1
