Answer:

x = - 7, x = 0, x = 7

Step-by-step explanation:

Given

x³ - 49x = 0 ← factor out x from each term

x(x² - 49) = 0 ← x² - 49 is a difference of squares, thus

x(x - 7)(x + 7) = 0

Equate each factor to zero and solve for x

x = 0

x - 7 = 0 ⇒ x = 7

x + 7 = 0 ⇒ x = - 7

In words:
Three sandwiches, each costing $5.25, equals 1/3 of Cassie's total money

We can write the formula:

(5.25*3)=1/3x

Now solve:

15.75=1/3x
3(15.75)=x
x=$47.25
Hope this helps!!
