(Car Sales) Of the cars sold during the month of July, 88 had air conditioning, 96 had automatic transmission, and 76 had power
Shalnov [3]

Answer:

Option E.

Step-by-step explanation:

Given information:

Air conditioning = 88

Automatic transmission = 96

power steering = 76

All three = 4

None of these extras = 19

Only air conditioning = 23

Only automatic transmissions = 61

Only power steering = 28

Both automatic transmission and power steering = 11

Place these values and draw a venn diagram as shown below.

Calculation for missing values:

11-4=7

96-61-4-7=24

88-24-4-23=37

From the given diagram it is clear that the number of cars that had air conditioning and automatic transmission but not power steering is 24.

Therefore, the correct option is E.

If 15% of an item is $18 what is the original price??
stiks02 [169]

Answer:

If you were trying to find 15% of 18, that would be multiplying a decimal, but, you need to mutliply a whole number. $120 should be your answer. People, correct me if I'm wrong (seriously though, not 100% sure if this is correct).

Step-by-step explanation:

18 = 15% x Y

18 = 15/100 x Y

Y = 18 × 100/15

Y = 18 × 100 ÷ 15

Y = 120

Setler [38]
We find the length of AD using the similarity of right triangle property. See image attached.

AD² = BD × CD
AD² = 9 × 36
AD² = 324
AD² = 18²
AD = 18

The length of AD is 18 units
