Teresa needs to save $25.50 to go to the movies this weekend. She currently has $3. If Teresa makes $7.50 an hour babysitting, how many hours does she need to babysit this week?

she needs to babysit for 3 hours this week.

Step-by-step explanation:

Let x represent the number of hours that she would babysit in a week.

She currently has $3. If Teresa makes $7.50 an hour babysitting. This means that if she babysits for x hours in a weeks, the total amount of money that she would have saved would be

7.5x + 3

Teresa needs to save $25.50 to go to the movies this weekend. This means that

7.5x + 3 = 25.5

7.5x = 25.5 - 3

7.5x = 22.5

x = 22.5/7.5

x = 3

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
