Answer: 25 grapefruits

Step-by-step explanation:

They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:

= 1 / 5

= $0.20 per grapefruit.

They then sell at a price of 5 per $3. The selling price per grapefruit is:

= 3 / 5

= $0.60

The profit per grapefruit is:

= 0.60 - 0.20

= $0.40

In order to make a profit of $10, they should sell:

= 10 / 0.4

= 25 grapefruits

If there 8 boys for every 7 girls with 195 total, how many are boys?

Lilit [14]

B = boys g = girls
.................................

b + g = 195 b = 195 - g

b = 8
g 7

Substitute b for 195 - g in the 2nd equation:

b = 8
g 7

195 - g = 8
g 7

Cross Multiply

8g = 7 . ( 195 - g )
8g = 1365 - 7g
8g + 7g = 1365
15g = 1365
g = 1365
15
g = 91

Substitute g for 91 in one of the equations:

b + g = 195
b + 91 = 195
b = 195 - 91
b = 104

S = 104 boys.

Ad libitum [116K]

The inequality is looking for a value of "at least 10" gardens. This means something "greater than or equal to" 10 (>=10). After selling 3 on Monday plus 4 on Tuesday, this leaves "x" to be sold to reach the goal. By setting this on the same side as the 7, we can create the inequality to find out how many more are needed, at minimum, to reach our stated goal: 7 + x >= 10, which, when subtracting the 7 out from both sides of the inequality, leaves x >= 3 gardens.
