Last year elissa contributed $105 per month toward her 401(k) account. if her employer matched 15% of her contributions, what was the total amount contributed to the 401(k) at the end of the year? a. $1162 b. $1575 c. $1449 d. $1442

105(12) = $1,260(.15) = 189
189 is the fifteen percent times the total amount at the end of the year, add it plus the year total, and you have (drumroll please) $1,449 total.

So C. $1,449

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
