Answer:
-19i + 26j
Step-by-step explanation:
-3 (5i - 6j) + 2 (-2i + 4j)
Distribute/multiply the -3 to everything in the parentheses
-15i + 18j + 2 (-2i + 4j)
Distribute/multiply the 2 to everything in the parentheses
-15i + 18j -4i + 8j
Combine like terms
-19i +26j
Answer:
$2561.99 a quarter
Step-by-step explanation:
Just add together what they pay every year, then multiply by 25.5% (because that's the quarterly premium.)
Annual cost = insurance + dental + vision
= 8900 + 772 + 375 = $10047 a year.
Quarterly cost = 25.5% of annual cost
Whenever you see of, think of multiplication!
25.5% = .255
Quarterly cost = .255 * 10047 = <u>$2561.99 a quarter</u>
