Juan ran the lemonade stand for 3 more days. each day, he used the money from sales to purchase more lemons, cups, and sugar to make more lemonade. on day 2, he earned $16 and spent $7 on supplies. on day 3, he earned $22 and spent $12. the expression 16 – 7 + 22 – 12 can be used to model the situation for these 2 days. identify the expression that uses adding the additive inverse to rewrite the expression. –16 + (–7) + (–22) + (–12) –16 + 7 + (–22) + 12 16 + (–7) + 22 + (–12) 16 + (–7) + 22 + 12

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
