The correct answers are:
A) 120 cards; and
B) $90.
Explanation:
Let x be the number of greeting cards sold that week. She earns $0.35 per card and earned $42; this gives us the equation
0.35x = 42
Divide both sides by 0.35:
0.35x/0.35 = 42/0.35
x = 120
She sold 120 cards.
She sells each card for $0.75. This means she earned
0.75(120) = $90.

Answer:
The number of parts on the four plots are 40.5
Step-by-step explanation:
The number of plots is 4 and each has an area of 12 acres, thus the total area is 36 acres.
Dividing them into a number, n, of parts gives;
where n is the number of parts.
= of an acre
Thus,
n = (36 × 9) acres ÷ 8 acres
= 324 ÷ 8
= 40.5
Thus it has been divided into 40.5 parts.
