PL HELPPPS ASA Dan earns $42.75 per month working as a tutor. He worked as a tutor for 4 months. He also earned $52.45 walking dogs in the neighborhood. He spent $18.50 of his total earning to buy a movie ticket and candy. Dan put 1 over 3 of the remaining money in his savings account.

Dan used the following steps to find the total money he put in his savings account:

Step 1: [($42.75 ⋅ 4) + $52.45 − $18.50] ⋅ 1 over 3

Step 2: [$171 + $52.45 − $18.50] ⋅ 1 over 3

Step 3: 241.95 ⋅ 1 over 3

Step 4: $80.65

In which step did Dan first make an error? Use words to explain how Dan can correct his error.

42.75 x 4 = 171

171 + 52.45 = 223.45

223.45 - 18.50 = 204.95

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
