Question

Maya has 155 stamps in her collection. If Sara were to double the number of stamps that she has, she would have more then Maya has.If s = the number of stamps that Sara has, which mathematical sentences expresses the information above? A. 2s > 155B. S/2 < 155C. S/2 > 155 D. 2s < 155

Answer 1

Let s represent the number of stamps Sara has.

For double the number of stamps, she has,

$2\times s=2s$

If Sara has more stamps than Maya after doubling her stamps, then,

$2s>155$

Hence, A is the answer.
