I HAVE30 min left help
frez [133]

Answer:

I think 10.5 would be the unit price and 10lbs of potatoes and 2lbs of tomatoes would cost less

Step-by-step explanation:

since tomatoes cost 2 times more I decided to act as he only bought potatoes and in that case he would have bought 22lbs of potatoes so I divided 16.50 by 22 and got .75 then I multiplied it by 10 and got 7.5 as well as multiplied .75 by two to get the price of the tomatoes then I added 7.5+3 to get 10.5

21. Tom buys a DVD player on 12 monthly payments. The cash price is $600. He pays
slamgirl [31]

Answer:

Each monthly payment is $ 49.05, and in total Tom paid $ 648.60.

Step-by-step explanation:

Given that Tom buys a DVD player on 12 monthly payments, whose cash price is $ 600, and he pays a 10% deposit and the store charges 9% interest, to determine how much is each payment and the total amount Tom pays for the DVD player the following calculations must be performed:

600 - 600 x 0.1 = 540

540 x 1.09 = 588.6

588.6 / 12 = 49.05

Thus, each monthly payment is $ 49.05, and in total Tom paid $ 648.60.

A marketing company is designing a new package for a box of cereal. They have determined that the function C(x) = 4.5 x2 models
Vlad1618 [11]

So the function is

\\ \rm\rightarrowtail y=4.5x^2

As we know

  • x²≥0
  • x≥0

hence domain is

\\ \rm\rightarrowtail D_f\in R

  • Least value of function is at x²=0 i.e 0

Hence range:-

\\ \rm\rightarrowtail R_f\in [0,\infty)
