 Amanda
follows a pattern for saving
money each week for one year. In
Week 1 she saved $1.00; in Week 2,

save $6.40? $8.80?
 A number
is doubled and then
increased by 300. Then 50 is
subtracted from the result. The final
number is 404. Find the original
number.
 The
sum of four decimals is 9. Each
decimal is 0.5 greater than the
previous decimal. What are the
decimals?
 The
product of 0.4 and another
decimal is less than 0.4 but greater
than 0.3. What are the least and
greatest decimals, to the nearest
hundredth, for the other factor?
 The
product of two whole numbers is
30. If 10 is added to the first number
and 8 is added to the second number,
the new product is 208. What are the
two numbers?
 Without
