Tim's phone service charges $24.78 plus an additional $0.24 for each text message sent per month. If Tim's phone bill was $30.78,
which equation could be used to find how many text messages, x, Tim sent last month?
OA. $0.24x - $24.78 = $30.78
OB. $0.24x + $24.78 = $30.78
OC. $24.78x - $0.24 = $30.78
OD. $24.78x + $0.24 = $30.78

answer: we have from thales theorem that because the 2 triangles are similar, jm/jk=jn/jl. we have that jn=x, jl=x+24 and that jm=7 and jk=28. substituting, we get:

x/(x+24)=7/28.

hence, x/(x+24)=1/4. this leads to 4x=x+24, 3x=24, x=8. we have solved for x=jn and this is equal to 8.
