Explanation:

Step1: Convert weights to decimals

$15\% = 0.15$, $16\%=0.16$, $17\% = 0.17$, $10\%=0.1$, $5\% = 0.05$, $37\%=0.37$

Step2: Multiply each grade by its weight

Test 1: $74\times0.15 = 11.1$
Test 2: $59\times0.16=9.44$
Test 3: $48\times0.17 = 8.16$
Homework: $79\times0.1=7.9$
Semester Project: $64\times0.05 = 3.2$
Final Exam: $85\times0.37=31.45$

Step3: Sum up the products

$11.1 + 9.44+8.16 + 7.9+3.2+31.45=71.25$

Answer:

$71.25$
