A grocery store reduced the price of a loaf of bread from $2.80 to $2.73. Find the percent decrease. Round your answer to one decimal place.

2.5%

Step-by-step explanation:

2.80 - 2.80x = 2.73

2.80x   price decrease.

Next solve for x.

-2.80x = -0.07

Divide both sides of the equation by -2.80.

x = 0.025

Finally, multiply this by 100.

x = 2.5

i would say b) is your answer

sorry if im wrong

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.
