Mrs. Hart spent 3/5 of her money on a bag and 1/6 on a belt. She had $14 left. How much money did she have initially?

klasskru [66]

Answer:

$60

Step-by-step explanation:

Let x represent the initial money she had

She spent 3/5 of her money on a bag, That is;

3/5 of x

= 3/5 * x

and 1/6 of x on a belt

Therefore, the total money she spent is

3/5 * x + 1/6 * x

She had $14 left after all her purchases

To find how much she had left, sum up all her spending and what she has left

3/5 * x + 1/6 * x + 14 = x

collect like terms

3/5 x + 1/6 x - x = -14

23/30 x -x = -14

-7/30x = -14

x = $60

A cellphone company charges $60 for a cellphone and a monthly rate to use the phone.Regina will pay $1,140 for a 24-month cellph

Alinara [238K]

The monthly rate is $45 for this cellphone plan.

Step-by-step explanation:

Given,

Amount charged for cell phone = $60

Number of months = 24

Let,

m be the monthly rate for cellphone plan

Number of months * Monthly rate + cellphone charges = Amount paid

$24m+60=1140\\24m=1140-60\\24m=1080$

Dividing both sides by 24

$\frac{24m}{24}=\frac{1080}{24}\\m=45$

The monthly rate is $45 for this cellphone plan.
