Question

shopping while shopping for clothes, jaclyn spent $30 less than 3 times what daniel spent. jaclyn spent $21. write and solve an equation to find how much daniel spent. let x represent how much daniel spent. the equation that can be used to determine how much daniel has spent is 3 x - 30 = 21. daniel spent $21.

Explanation:

Step1: Set up the given equation

$3x - 30 = 21$

Step2: Isolate the term with $x$

Add 30 to both sides:
$3x - 30 + 30 = 21 + 30$
$3x = 51$

Step3: Solve for $x$

Divide both sides by 3:
$x = \frac{51}{3}$
$x = 17$

Answer:

The equation that can be used to determine how much Daniel has spent is $3x - 30 = 21$.
Daniel spent $\$17$.
