Question

Helen earned $400 in January, $450 in February, and $380 in March. To pay all of her bills, she must average at least $430 per month. For what income in April would her average for the four months be at least $430 *

1 point

A.400+450+380+x ÷ 4 ≥ 430 ––> x≥490

B. 400+450+380+x÷4 > 430 ––> x>490

C.400+450+380+x÷4 ≤ 430 ––> x≤490

D.400+450+380+x÷4 < 430 ––> x<490

Answer 1

Never mind, the answer is for sure A . I got the question right.

Answer 2

To find the income Helen needs in April to have an average of at least $430 per month over the four months, we can use the following equation:

(400 + 450 + 380 + x) / 4 ≥ 430

This equation represents the average income over the four months being greater than or equal to $430.

Simplifying the equation, we get:

1230 + x ≥ 1720

Subtracting 1230 from both sides, we have:

x ≥ 490

Therefore, the correct answer is:

A. 400 + 450 + 380 + x ÷ 4 ≥ 430 ––> x ≥ 490
