Jimmy and Jack stop at separate street vendors on their way to work one day.
The stand where Jimmy stops sells a
refillable soda for $2 and pretzels for $2
each. Jack stops at a vendor that sells
pretzels for $1.50 each. Jimmy purchases
the same number of pretzels as Jack and
also spends the same amount of money.
Find x, the number of pretzels they each
purchase.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
