Jimmy is a tutor in the science club. He charges $40 per semester to privately tutor other students and an additional $10 for home visits to help him pay for gas. If Jimmy made less than $80 this semester for tutoring 1 student, which inequality can be used to determine how many times he visited the student's home?

Step-by-step explanation:

Let

x ----> the number of  home visits in a semester

we know that

The linear equation in slope intercept form is equal to

we have

substitute

Remember that

Jimmy made less than $80 this semester for tutoring 1 student

so

the inequality that represent this problem is equal to

solve for x

subtract 40 both sides

divide by 10 both sides

therefore

The number of visits is less than 4

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
