Answer: 2.5%

3967.50 - 3450 = 517. 50

i = prt/100

i = 517.50, p = 3450, t = 6

517.50 = 3450 x r x 6/ 100

517.50 = 20700r/100

517.50 = 20700r

517.50/20700 = r

r = 0.025 = 2.5%

While shopping for clothes, Tracy Spent $38 less than 3 Times what Daniel spent. Write and solve an equation to find how much da

Mamont248 [21]

Answer:

$16

Step-by-step explanation:

Let $x be the amount of money Daniel spent.

Tracy spent $38 less than 3 times what Daniel spent.

Daniel spent = $x

3 times what Daniel spent = $3x

$38 less than 3 times what Daniel spent = $(3x-38)

So,

Tracy spent = $(3x-38)

If Tracy spent $10, then

$3x-38=10\\ \\3x-38+38=10+38\ [\text{Add 38}]\\ \\3x=48\\ \\x=16\ [\text{Divide by 3}]$

Hence, Daniel spent $16
