Question

Raul plans to spend $78 on two shirts and a pair of jeans. He bought two shirts for $19.89 each. How much can he spend on the jeans?

Answer 1

Help.

Answer 2

Given what's spent the equation is $78=2*$19.89 + x. X stands for the rest of the money (which Raul can spend on jeans).
Now solve for x: \[x=$78-2 $19.89=$38.22\]

Answer 3

Ty but what is the second equation?

Answer 4

that's the first equation rearranged to separate x. This is how one solves for an unknown (x). The result is that x equals $38.22.

Answer 5
