Ahmed wants to buy one of two skateboards. One skateboard costs $1 more than the other. The sum of their costs is $145. How much does each skateboard cost.

Take 145, take away 1$ then divide by 2 considering there are 2 skateboards, then that leaves you with 2 72's or 72 and 72 then add the one back leaving you with 72 and 73

Hope this helped!

Answer:

$72 and $73

Step-by-step explanation:

Step 1: Turn the question into words

[tex]s_1+s_2=145\\s_2=s_1+1[/tex]

Step 2: Rearrange the equations a bit

[tex]s_1+s_2=145\\-s_1+s_2=1[/tex]

Step 3: Subtract the second equation from the first

[tex]2s_1=144[/tex]

Step 4: Divide both sides of the equation by 2

[tex]s_1=72[/tex]

Step 5: Find s2

[tex]s_2=s_1+1\\s_2=72+1\\s_2=73[/tex]

Step 6: Conclude

One skateboard costs $72 and the other skateboard costs $73.
