Question 1
Leo sold candy bars for a fundraiser. He spent $25 on a box of candy bars and sold them for $2 each. If his profit (after earning back the $25) was $69, how many candy bars did Leo sell?

Which equation can be used to solve the problem?

1. $2c+$25=$692 dollars plus 25 dollars is equal to 69 dollars

2. $2c=$69−$252 dollars is equal to 69 dollars minus 25 dollars

3. $25−$2c=$6925 dollars minus 2 dollars is equal to 69 dollars

4. $2c−$25=$69

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
