One movie club charges $100 membership fee and $10 per movie. Another club charges no membership fee but movies are $15 each. Write and solve an equation to find the number of movies you need to buy for the cost of each movie club to be the same?Write the equation_____________

Answers

the first club charges 100 dolars staarting fee and 10 dollars per movie so
100+10x
x represents how many times they go

second club 15x

so we want to find out whenthey will be equall so

100+10x=15x
subtract 10x from both sides
100=5x
divide both sides by 5
20=x
so you need to go 20 times to get the same value

Last year, Austin, Texas received 23.5 inches of rainfall. This year, Austin received 21.2 inches of rainfall. Find the percent of decrease in the number of inches of rainfall. Round your answer to the nearest tenth of a percent, if necessary.

Answers

Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %

Calculate x:
$x = (21.2 \cdot 100)/(23.5) = 90.212766$ , which is around 90.2%.

The percent of decrease is 100 - 90.2 = 9.8 %.

What is system of linear equations?

A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.

What is substitution method?

The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.

According to the given question.

Cost of one packet of basil seeds = $1.50

Cost of one packet of squash seeds = $2.50

Cost of 18 packets of seeds = 38

Also, b represents the number of packets of basil seeds and s represents of numbers of squash seeds.

Therefore, from the given conditions we get some system of equations

$s + b = 18..(i)$
