Jackie wants to earn $380 this summer by babysitting and dog walking. She earns $40 each time she babysits and $25 each time she walks dogs. This situation can be represented by the equation 40x + 25y = 380. Use the equation to determine whether or not Jackie will earn $380 if she babysits 7 times and walks dogs 4 times.

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.
