Answer:
a30 = 96
Step-by-step explanation:
-20,-16,-12,-8,-4
We are adding 4 each time, which is the common difference
-20+4 = -16
-16+4 =-12
The formula for an arithmetic sequence is
an = a1 +d(n-1) where a1 is the first term and 4 is the common difference
an = -20 +4(n-1)
We want the 30th term
a30 = -20+4(30-1)
a30 = -20 +4(29)
= -20 +116
= 96
If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50% convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.
You look for certain key words. The expression "at least" means "greater than or equal to." The expression " is no more than" means "less than or equal to." A sum means an addition. A difference is a subtraction. There are many other words that you need to look out for and translate into math symbols.
