Answer:
The minimum number of cups she must sell to reach her goal=43 cups
Step-by-step explanation:
Total earnings=Total Lemonade sales-Supplies expenditure
where;
Total earnings=$40
Total Lemonade sales=Price per cup×Number of cups sold(n)=(0.7×n)=0.7n
Supplies Expenditure=0.23 per cup=(0.23×n)=0.23n
Replacing;
40=0.7n+0.23n
Inequality; 0.7n+0.23n=40
Solving;
0.93n=40
n=40/0.93)=43 cups
The minimum number of cups she must sell to reach her goal=n=43 cups
