Beth swam laps to raise money for a charity. beth raised $15 plus $0.65 per lap that she swam. she raised a total of $80.00. let x represent the number of laps beth swam. what expression completes the equation to determine the total number of laps beth swam? how many laps did beth swim?

Answer

Find out the how many laps did Beth swim and write expression the  total number of laps Beth swam .

To proof

As given

Beth swam laps to raise money for a charity.

Beth raised $15 plus $0.65 per lap that she swam.

She raised a total of $80.00

Let x represent the number of laps Beth swam.

Than the expression becomes

15 + 0.65× x = 80 .00

Simplify

15 + 0.65x = 80

0.65x = 80 -15

0.65x = 65

x = 100

Therefore the number of laps did Beth swim be 100 .

Hence proved

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
