•
The answer is $7.75
To find change, subtract money he has minus
money he spent. He spent $2.25 (1.50+0.75).
Then subtract $10.00 - $2.25

in the blanks
4, 16, 64, ____, ____
Patterns & Functions
• The rule is to multiply by 4
(4 x 4 = 16; 16 x 4 = 64)
The next two numbers are 256 and
1,024
(64 x 4 = 256 and 256 x 4 = 1,024)

Mark spins a spinner. There are 4 red spaces,
3 green spaces and 5 blue spaces. What
fraction shows the probability that the
spinner will land on red?
1/4
1/3
1/2
1/5
Probability
•
The answer is 1/3. Since there are 12
spaces on the spinner, and 4 are red,
the probability of landing on red is
4/12. When we divide numerator and
denominator by 4, we get 1/3 as an
equivalent fraction

• Part 1: ? = 6
The rule in this chart is to multiply x by
8 to get y. This can be written as x
x 8 = y. To get y to equal 48, you
must multiply 6 x 8. Therefore the
question mark is equal to 6!
1,000,000 Answer
• Part 2: When x is 10, y = 80
When you plug in 10 in the x-column,
you get 80 as y. Since the rule is
multiply by 8, you are doing 10 x 8
to get your y-value of 80!
