Answer:
$5.88

A = $ 5.88
Answer:
see below
Step-by-step explanation:
Proportion:
4.41 is to 3 erasers as 'x' is to 4 erasers:
<u>4.41 /3 = x / 4 <======this is your proportion</u>
<u> or rearrange </u>
<u> 4 * 4.41/3 = x </u>
(this results in x = $ 5.88 for 4 erasers )

how long is |MN| when you measure it and do you know anything about the length of |NO| and |OP|?
assuming |MN|= 7.7 ; |NO|= 4.7 ; |MO|= 5.5:
o²= m²+n²
= 4.7²+5.5²
=52.34
o=V52.34
≈7.23
