Answer:
Peter should join <u>Lab thinkers</u> to receive a better deal.
Science buddies costs <u>190$</u> for six months.
Lab thinkers costs <u>170$</u> for six months.
Step-by-step explanation:
The equations are...
Science buddies: 10+30x -> 10+30(6)=190
Lab thinkers: 45+25x -> 45+25(6)=170
Peter saves 20$ if he chooses lab thinkers.
Sorry for my mistake, this is my new edit.
The percentage by which the cost is increasing will be 75%.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The percentage of the 8th graders who want to go to the water slides is found from;
In the year 2000, a house was valued at $60 000.

Step-by-step explanation:
Given, 3x−2<2x+1
⇒3x−2x<1+2
⇒x<3orx∈(−∞,3)
The lines y=3x−2 and y=2x+1 both will intersect at x=3
Clearly, the dark line shows the solution of 3x−2<2x+1.
