betty earns $52.65 per week working as a lifeguard. she worked as a lifeguard for 5 weeks. she also earned $46.25 painting faces at a carnival. she spent $16.25 of her total earnings to buy a book. betty put of the remaining money in her savings account.
betty used the following steps to find the total money she put in her saving account:
step 1: [($52.65 ⋅ 5) + $46.25 − $16.25] ⋅
step 2: [$263.25 + $46.25 − $16.25] ⋅
step 3: 293.25 ⋅
step 4: $1,759.50
in which step did betty first make an error? use words to explain how betty can correct her error.

Betty made a mistake when she times her money with 1/6. That happened in step 3. Her answer was wrong. If you times 293.25 with 1/6 you get 48.875 not 1,759.50. If Betty went back and fixed her mistake she would have the right answer.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
