Answer:
B and C
Step-by-step explanation:
We can just solve each to find which expressions are equal to 1.5.
A) 0.15 × 100 = 15
B) 15.0 ÷ 10 = 1.5
C) 0.15 × 10 = 1.5
D) 0.15 ÷ 10 = 0.015
E) 1.5 ÷ 100 = 0.015
From our results, we see that B and C are the only answers that equal 1.5.
Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.
Then,
52x + 34y = 1150 --- (1)
Also, she has six more 34 cent stamps than 52 cent stamps.
Therefore, y = x + 6
(1) becomes
52x + 34(x + 6) = 1150
52x + 34x + 204 = 1150
86x + 204 = 1150
86x = 1150 - 204
86x = 946
x = 11
and y = 11 + 6 = 17
Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.
