Melia put the $20 her Grandmother gave her for her tenth birthday into her piggy bank. Each week after that she added her $1.50
kondaur [170]
<h3>Answer: a) Equation y= 20+ 1.50n.</h3><h3>b) Melia have $644 to spend on her 18th birthday.</h3>

Step-by-step explanation: We are given that Melia put $20 initially in piggy bank.

Each week amount added in piggy bank = $1.50.

Let us assume total number of weeks be n Melia added amount in piggy bank and get y amount after n weeks.

a) Therefore, total amount after n weeks = Initial amount + 1.50 times n weeks.

y= 20+ 1.50n.

b) On 18th birthday, there would be total 8 years after 10th birthday.

And in 8 years there would be 52 × 8 = 416 weeks.

So, in order to find the total amount after 8 years or 416 weeks, we need to plug n= 416 in the equation we got in a part.

Therefore,

y = 20+ 1.50(416)

y = 20 + 624 = 644.

<h3>Therefore,  Melia have $644 to spend on her 18th birthday.</h3>
