Step-by-step explanation:

Kat wants to use her money to support animals at a shelter after receiving her pay check from work . She pays $15 per animal, and leaves $20 for the workers. She can spend at most $130. How many animals can she help?

Solve for x

$15x-20\leq 130$

Add 20 to both sides to isolate x

$15x-20+20\leq 130+20\\15x\leq 150$

Divide each side by 15

$\frac{15x}{15}\leq \frac{150}{15} \\\\x\leq 10$

Kat can help at most 10 animals.
