Question

Roberto has $200 in spending money. He wants to buy some video games that cost $25.50 each. Write and solve an inequality to find the number of games that Roberto can buy.

Answer 1

Step-by-step explanation: Each game is $25.50 which in math means it has an "x"

So if x=1 then 25.50x says that 1 video game is $25.50

Set up the equation:

200 = 25.50x (divide both sides by 25.50 to isolate the x)

200/25.50 = 7.84

x = 7.84

You can't have 0.84 of a video game, so Roberto can only buy 7 of them.   The answer is correct good job!

Answer 2

The number of games that Roberto can buy $\boldsymbol{8}$ video games.

Solve an Inequality

When two values are compared, an inequality shows whether one is less than, greater than, or simply not equal to the other.

It's a relation that compares two integers or other mathematical expressions in a non-equal way.

Total amount with Roberto $=\ 200$

Let $x$ denotes number of games that Roberto can buy.

Cost of each video game $=\ 25.50$

So,$25.50x\leq 200\\x\leq 7.8$

Therefore, Roberto can buy $\boldsymbol{8}$ video games.
