Let x equal the # of coach tickets
Let y equal the # of first class tickets
x + y = 16
260x + 970y = 10,550
Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.
x + y = 16
x = 16 - y
Now substitute the resulting expression into the other equation and solve for y.
260( 16 - y ) + 970y = 10,550
4160 - 260y + 970y = 10,550
Combine like terms
4160 + 710y = 10,550
Subtract 4160 from both sides
710y = 6390
divide by 710
y = 9
Substitute the value of y into the equation that we solved for x, x=17−y.
x = 17 - 9
x = 8
Therefore the answer is, 8 coach tickets and 9 first class tickets.
Answer:
They can both do 35 push-ups per minute, with an equal ratio between them.
Step-by-step explanation:
Given that Nora can do 70 push-ups in 2 minutes, and Luke can do 105 push-ups in 3 minutes, to determine if these rates from a proportion the following calculation should be performed:
70/2 = X
35 = X
105/3 = X
35 = X
Therefore, they can both do 35 push-ups per minute, with an equal ratio between them.

Hi there:)
start off with the gross.
8.35×16=133.6
Total tax rate is
7.65+9.15+7.5=24.3%
Tax
133.6×0.243=32.4648
Subtract the tax from gross
133.6−32.4648=101.1352
Deducte your expenses
101.1352−(6.30×4)
=75.94 this is your net income
Hope it helps
