Answer:
She needs 64 ounces of flour.
Step-by-step explanation:
If she needs 4 pounds and it is in ounces you would multiply 16 and 4 which gives you 64 ounces
You need to multiply 21 by $4.65, which gets you $97.65
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
4 squared is the answer to this equations
