Alison bought 12 shares in the toy company when it cost $27. she is planning on selling her shares and they currently cost $39.50. what is the percent increase in sale price (round to the nearest percent)?

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

the answer is 489

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
