If 65% of a number is 234 and 10% of the same number is 36, find 75% of that number.

270

Step-by-step explanation:

65/100 × x = 234. eqn 1

10/100 × x = 36 eqn 2

75% of x = ?

we need to find x in one equation and cross-check in the other so we can answer the question.

65/100 × x = 234

65 × x = 23400

x = 23400 ÷ 65

x = 360

cross-check in eqn 2

10/100 × x

10/100 × 360 = 36

that means x is 360

75/100 × 360 = 270

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
