Justin has $7.50 more than eva and emma has $12 less than justin. together, they have a
total of $63.00. how much money does each person have?

To make it easier, lets say Justin = J, Eva = E, and Emma = M. Then, J = E + 7.50 M = J -12 J + E + M = 63 You can substitute for M in the third equation using the second equation, and you get: J + E + J - 12 = 63 Clean it up a little bit and you get: 2J + E = 75 You know J = E + 7.50, so substitute that for J and you get: 2(E + 7.50) + E = 75 2E + 15 + E = 75 3E + 15 = 75 3E = 60 E = 20 ; meaning that Eva has $20. Justin has $7.50 more than Eva, so he has $27.50. Emma has $12 less than Justin, so Emma has $15.50. Double check your answer by making sure they all add up to 63, which they do.

If Eva has x dollars, Justin has (x + 7.50) and Emma has (x + 7.50 - 12) = (x - 4.50) dollars. So, x + (x + 7.50) + (x - 4.50) = 63 => 3x + 3 = 63 => x = 20 So, Eva has $20, Justin has $27.50 and Emma has $15.50.

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
