Mr. Smith is paid $9.50 per hour for fixing watches. Write an expression for the amount of money Mr. Smith earns in h hours. In addition to his hourly rate, Mr. Smith is paid $2.20 for each watch he fixes. Write an expression for his income if he fixes r watches per hour.

1. 9.5h

2. 2.2r + 9.5h

Step-by-step explanation:

This is the correct way to write the expression. Based on the order of operations, always solve operations in parentheses first. Here, you'd add 4 + 2, then multiply that sum by 5—in other words, exactly what was written in the original expression.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
