Answer:

Plan A

Step-by-step explanation:

Gina plans to use less than 500 minutes each month.

The cost four plans are given in the table.

Let's find the cost of each plan assuming that Gina use 500 minutes.

Plan cost = Monthly fee + const per minute

Plan A cost = $15 + 500*0.05 = $15 + $25 = $40

Plan B cost = $5 + 500*0.15 = $5 + $75 = $80

Plan C cost = $10 + 500*0.10 = $10 + $50 = $60

Plan D cost = $20 + 500*0.20 = $20 + $100 = $120

By comparing the price, the Plan A is cost effective plan.

therefore, the answer is  Plan A.

Ashton needs $120 but has only saved 60% so far. How much more money does he need
Kamila [148]

Hello there! Ashton needs 48 more dollars.

Well, to start, you want to find 60% of 120. To do this, you first have to convert 60% into a decimal by dividing it by 100.

60/100 = 0.6

Next, multiply 0.6 by your total needed, 120, to finish finding 60% of 120.

120 x 0.6 = 72.

So he already has 72 dollars, but how many more does he need? You can find this by subtracting 72 from 120.

120 - 72 = 48.

So, this means he needs 48 more dollars. I hope this helps and have a great rest of your day! Please let me know if you need further help with this question. :)

Christine is putting money into a savings account. She starts with $650 in the savings account, and each week she adds $60. Let
TEA [102]

Total amount of money in the savings account after 11 weeks is $1310.

Total money in the account =

 Initial Money + Money added per week x Number of weeks

Given:

Initial Money = $650

Money added per week = $60

Total money in the account = S

Number of weeks = W

Substituting it in the above equation we get,

S = $650 + $60xW                                          (General Equation)

Total amount of money in the savings account after 11 weeks

S = $650 + $60x11

S = $650 + $660

S = $1310

Thus total amount of money in the savings account after 11 weeks is $1310.
