Question

Pre algebra help. Maria earns $8 an hour babysitting. Last week Maria made $64. She needs to have at least $150 for vacation. Which inequality can be used to determine how many more hours Maria needs to babysit before she is ready for vacation? 1. 64x + 8 < 150 2. 8x + 64 < 150 3. 8x + 64 > 150 4. 64x + 8 > 150

lucaz · Answer

she already has $64, and she earns $8/h, it would be 8x + 64, when you say at least the sign should be "greater than or equal to", but the right option is 8x+64>150
