Help plzz (30) points for both of the question-plz help - this is life or dead answer

Elodia [21]

Answer:

The answer is B) 11.

Step-by-step explanation:

We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):

$2.3x + 4.3 + 0.4 = 30$

$2.3x + 4.7 = 30$

$2.3x + 4.7 - 4.7 = 30 - 4.7$

$2.3x = 25.3$

$2.3x/2.3 = 25.3/2.3$

$x = 11$

Lee and Lyn both invested their birthday money. Lee put his money in a savings account that earned 8% simple interest annually.

tatyana61 [14]

Lyn made a better investment.

Her money will grow quicker than Lee because the money grows by 8% annually, and then the next year 8% off of the new balance.

Lee's money will only grow by 8% from the original price.
