A store sells gravel and small bags and large bags. The small bags have 6 pounds of gravel for $35.88 in the large bags have 15 pounds of gravel for $81.75 ,write an equivalent fraction that gives the unit rate of price per pound for each bag.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

$79500

step-by-step explanation:

it's d

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
