Two plans for reaching a goal are given below. plan a: save $450 over the next 8 weeks by working 9 hours per week at $7.20 per hour. plan b: save $450 over the next 6 weeks by working 15 hours per week at $6.50 per hour. which of the following is a true statement? a. only plan a will work for achieving the goal. b. only plan b will work for achieving the goal. c. both plans will work for achieving the goal. d. neither plan will work for achieving the goal.

The correct option is C) Both plans will work for achieving the goal.

Step-by-step explanation:

Consider the provided information.

Plan A: Save $450 over the next 8 weeks by working 9 hours per week at $7.20 per hour.

For next 8 weeks by working 9 hours per week at $7.20 per hour, you will earn:

We need to save $450 which is less than $518.40. Thus, plan A will work.

Plan B: Save $450 over the next 6 weeks by working 15 hours per week at $6.50 per hour.

For next 6 weeks by working 15 hours per week at $6.50 per hour, you will earn:

We need to save $450 which is less than $585.00. Thus, plan B will work.

Hence, the correct option is C) Both plans will work for achieving the goal.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
