Answer:
josh vendió 17 libros recaudando 306 dolares .
jessica vendió 255 libros recaudando 4590 dolares.
Step-by-step explanation:
Sustituimos por variables :
libros que vendió Jessica = x
libros que vendió Josh = y
entonces:
x + y = 272
Jessica vendió 15 veces mas libros que josh:
x = 15y
Reemplazamos en la anteriior ecuacion:
15y +y = 272
16y = 272
y = 17
Reemplazamos en la primela ecuacion :
x + 17 = 272
x = 255
Scientific notation means to write the answer in standard form. standard form helps you to express numbers that are too big or too small to be conveniently written in decimal form.
so for this case, it will be 4.571×10^-4.
when the number is decimal, you move the dot to the right and it will always be multiplying 10 to the power of a negative power.
