Sharon is working her way through school. she works two part-time jobs for a total of 35 hours a week. job a pays $6.10 per hour, and job b pays $7.40 per hour. how many hours did she work at each job the week that she made $235.60.

Sharon works at job A and job B for 18 and 17 hours respectively.

SOLUTION:

Given, Sharon is working her way through school.  

She works two part-time jobs for a total of 35 hours a week.  

Job A pays $6.10 per hour, and Job B pays $7.40 per hour.  

We have to find how many hours did she work at each job the week that she made $235.60.

Now, let the number of hours worked at A be "t", then number of hours worked at B will be 35 – t hours.

Now, according to the given information,  

6.1 x t + 7.4 x (35 – t) = 235.6

6.1t + 35 x 7.4 – 7.4t = 235.6

7.4t – 6.1t  = 259 – 235.6

1.3t = 23.4

t = 18

So, she works 18 hours at A, then, she works 35 – 18 = 17 hours at B.

Hence, Sharon works at job A and job B for 18 and 17 hours respectively.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
