Answer:

Katherine need to work minimum 10 hours lifeguarding to meet her requirements

Step-by-step explanation:

Given:

Rate for Lifeguarding = $$16\ per\ hour$

Rate for walking dogs = $$6 \ per\ hour$

She had worked 2 hours walking dog

Money for walking dogs = Rate for walking dogs $\times$ hours worked= $\$6\times2=\$12$

she can work a maximum of 15 total hours and must earn at least $160.

Let hours required for lifeguarding be x

Money for life guarding = Rate for walking dogs $\times$ hours worked for lifrguarding= $\$16 \timesx=16x$

Total Money she must earn = Money for lifeguarding + Money for walking dogs

$16x+12=160\\16x=160-12\\16x=148\\x=\frac{148}{16}=9.25 \ hours$

Rounding to nearest hour

Katherine need to work minimum 10 hours lifeguarding to meet her requirements
