Step-by-step explanation:
what is the problem ? we just follow the text to the letter.
first, we use 3/5 of the earnings to pay the bill.
that means only 5/5 - 3/5 = 2/5 of the earnings are left to do something else.
how much is 2/5 of $4,283.30 ?
that is written and calculated
$4,283.3 × 2/5 = $1,713.32.
so, she has $1,713.32 left after paying the bills.
from that amount of money she bought 2 shirts ($19.99 each) and a pair of sunglasses ($12.99).
to see how much she has left now, we need to subtract these 3 expenses from the available money :
$1,713.32 - 2×$19.99 - $12.99 =
$1,713.32 - $39.98 - $12.99 = $1,660.35
so, she has $1,660.35 left.
