first question

Kristen make $16 per hour

last week he worked for 34 hours

1 hour ==== $16

35 hours ==== $x

cross multiplication

x * 1 = 16 x 34

x = $544

Second question

for mark

make $14 per hour

he worked 46 hours last week

total amount made

1 hour ===== $14

46 hours =====$x

1 * x = 14 x 46

x = $644

Mark make $644 last week

for the fourth question

if mark and kristen combined their savings

mark make $644 and kristen make $544

their saving combines is

$644 + $544

= $1,188

Their saving combines is $1, 188

if mark works for 46 hours and make $644

if marks works for 34 hours and make $544

how many hours will they work

let the number of hours be x

equating the two equation
