She will earn $920 after working 40 hours.

Step-by-step explanation:

Given,

Amount per hour = $20

Raise = 15%

Raise amount = 15% of Amount per hour

$Raise\ amount = \frac{15}{100}*20\\Raise\ amount= \frac{300}{100}\\Raise\ amount= \$3$

New amount per hour = Amount per hour + raise amount

New amount per hour = 20+3= $23

Total earning after working 40 hours = Amount per hour * 40

$Total\ earning=23*40\\Total\ earning= \$920$

She will earn $920 after working 40 hours.

Let the number of large bookcases be x and number of small bookcases be y, then
Maximise P = 80x + 50y;
subkect to:
6x + 2y ≤ 24
x, y ≥ 2

The corner points are (2, 2), (2, 6), (3.333, 2)
For (2, 2): P = 80(2) + 50(2) = 160 + 100 = 260
For (2, 6): P = 80(2) + 50(6) = 160 + 300 = 460
For (3.333, 2): P = 80(3.333) + 50(2) = 266.67 + 100 = 366.67

Therefore, for maximum profit, he should produce 2 large bookcases and 6 small bookcases.

Nitella [24]

Answer:

Th number of pages is 33

Step-by-step explanation:

The ratio of the number of pages of text shown in the illustration is 3:2. This implies that for every 2 pages of illustrations, there are 3 pages of text. Therefore, for 22 pages of illustration we shall have;

2 page of illustration = 3 page of text

Then

22 page of illustration = x pages of text

Then by Cross multiplication

$22 \times 3 = x \times 2$
