- Scr0380: the forever and repeat
The second program uses a
forever block in conjunction with an
embedded
if block and a counter variable to create a counter loop.
That program was used as the jumping-off point for a discussion of thesimilarities and differences between a
forever/if block combination and a
repeat block.
The third program uses a
repeat until block to cause a sprite to run
in a small circle until the user pressesthe space bar. I pointed out that
unlike the
forever block, it is possible to connect another block to
the bottom of a
repeat until block. Therefore, it is not necessary for a
repeat until block to be the last block in a script.
Finally, I provided the specifications for a student-programming project for
you to demonstrate your understanding of what you learned from the threeprograms listed above and from earlier modules.
What's next?
One of the new features of Scratch v2.0 is the ability for you to create your
own blocks. The next module will discuss that feature.

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.

no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500
