Tony made $396 for 18 hours of work at the same rate how many hours would he have to work to make $198
tresset_1 [31]

Answer:

9 hours.

Step-by-step explanation:

So, first, you have to determine what he makes per hour to make this as easy as possible. You need to first do 396 divided by 18, which gives you 22. He makes 22$ an hour. Next, now that you know what he makes, you can do 198 divided by 22, and that'll show how long he has to work to make that amount of money.

Hope this helped. Please mark this brainliest if you think this helped. Let me know if you need anymore help and I am more than happy.

There are 59 people going on a field trip.
Maru [420]

You first multiply 6 and 8 to see how many people are put in the vans without rented a van. This would equal 48. You then subtract 48 from 59 to see how many people still need to be in a van. This would leave you with 11 people. Then you divide 8 from 11 to get 1 3/8. This means you need 2 vans to fit everyone.

Yuliya22 [10]
T=xd+ym\\x(4)+y(100)=(120)\\x(1)+y(240)=(80)\\\\4x+960y=320\\4x+100y=120\\860y=200\\y=\frac{200}{860}\\y=\frac{10}{43}\\\\x+240(\frac{10}{43})=80\\x+\frac{2400}{43}=\frac{3440}{43}\\x=\frac{1040}{43}

x = 1040/43 = $24.19 per day.

y = 10/43 = $0.23 per mile.
