Jane’s mobile phone plan charges $0.05 per minute at daytime rates before 8 p. m. and $0.03 per minute at nighttime rates after 8 p. m. A conference call costs 1.5 times the normal rate. Calculate the cost of a conference call lasting from 7 p. m. to 8:30 p. m.

Minutes at daytime rate:
Minutes at nighttime rate:
Total cost:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

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.

look at the picture i have filled out a table for it. hope this .
