Hope it helps
<h2>=============================</h2>
a + m = 30
a = m - 8
(m - 8) + m = 30
2m - 8 = 30
2m = 30 + 8
2m = 38
m = 38/2
m = 19
a = m - 8
a = 19 - 8
a = 11
so Amy has $11 and Maria has $ 19
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.
Then, using the circle area formula, the area of the 1/9 circle would be:
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57
$54 is your answer
You multiply $12.00 by 4 packs of pens and then add $6.00 for the pencils.
