Answer:
$10
Step-by-step explanation:
Subtract the price of the keychain, $7, from the total to find the price of the 3 t-shirts:
$37 - $7 = $30
The 3 t-shirts cost a total of $30.
We assume all t-shirts have the same price.
price of 1 t-shirt = $30/3 = $10
Answer: $10
She started with x.
After 1 year, she had 1.025x.
She withdrew <span>£1000, so now she has 1.025x - 1000.
Then it earned interest for 1 year and ended up as </span>1.025(1.025x - 1000).
The actual amount of money was £23 517.60.
Therefore,
<span>1.025(1.025x - 1000) = 23517.60
1.025x - 1000 = 22 944
1.025x = 23 944
x = 23 360
Her original deposit was </span><span>£23 360</span>
