In a bakery, a bag of bread rolls cost x dollars. a loaf of multi-grain bread costs $2 more than a bag of bread rolls. mr. lopez pays $50 for some multi-grain loaves of bread. write the number of loaves of bread he buys in terms of x.

Step-by-step explanation:

Cost of bag of bread rolls is x

Multigrain is (+2) more.

So (x+2)

Y can be the number of multigrain loves Mr. Lopez buys.

y=50/(x+2)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
