Althea's plans for saving $384 plan amount to save number of each week weeks needed $20 $30 $50 20 using plan b, how many weeks will it take althea to reach her savings goal? write an equation to model your work

13 weeks

Step-by-step explanation:

In the picture attached, data of the problem is shown in a table.

Althea wants to save $384, in plan B she saves $30 each week. The amount of weeks needed is obtained dividing the total amount to save by the amount saved per week, that is:

equation: $384÷$30  = 12.8 weeks

Here, weeks are considered integers, so you have to round this value to the next integer, that is, 13 weeks. To better understand this, suppose you take 12 weeks saving $30 per week, after 12 weeks you will save: $30*12 = $360, which is not enough; with 13 weeks you will save: $30*13 = $390.

a.)the line for function b is steeper

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
