Zoey and her children went into a grocery store where they sell apples for $2.25 each and bananas for $1.50 each. Zoey has $15 to spend and must buy a minimum of 7 apples and bananas altogether. Let x represents the number of apples purchased and y represents the number of bananas purchased so : Zoey can buy apples and bananas or

Zoey could buy 2 apples and 7 bananas.

Step-by-step explanation:

Since the point (2, 7(2,7) is inside the double shaded region, one possible solution to the system of inequalities would be:

a

b

d

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.
